For the guys shooting 2 blade broadheads, do you prefer a concave, convex, or straight design?

Bear razorhead they have stood the test of time. I guess there convex but never gave it much thought.
straight...I find them easier to sharpen.
I like the VPA 2 blades, but I'm a little biased.

P.S. In all seriousness, our 2 blades are an excellent broadhead. If you have any questions about them, let me know. Lots of other good 2 blades out there too. I think if I wasn't so impressed with the VPA's, I would be shooting a Grizzly 2 blade. I looked at them while up at the K-Zoo show and Bill really has them looking good. So they're another one to check out.
I have shot both convex and straight edge 2 blades and really can't tell a difference in them. I think the width and length of a broadhead is what really makes the difference.
I REALLY like my GK Silverflame XL's. I guess they would be considered convex.

Convex is my preference.
I prefer straight. Easier to sharpen for me.
Which ever one you can get the sharpest.
I like straight.
I really like Silver Flames convex blade, but I had difficulty getting a consistent edge. I changed to the ABS Samurai with a straight blade...much easier to sharpen.
Ace broadheads are awesome. Cheap, easy to sharpen, fly great and are super durable. Love them.
I am shooting the Simmons Treesharks. so a definite concave edge there...
Straights are easier to sharpen for me and what I normally hunt with. Convex is probably the toughest point; convex looks cool. They all work quite well.
Simmons heads for me with a concave edge!! They create larger holes than straight or convex.
I've tried several over the years but always seem to come back to straight and wide the Zwicky Delta and Magnus being the best. The ACE standard would be my next choice, convex, but still easy to sharpen. The concave, such as the Howrd Hill style, is good in theory but I found it very difficult to sharpen. Tom Mussatto, who had a great tutorial on sharpening these heads, may contest that point.

Straight for me. STOS and Abowyer are my favs, a long cutting edge work well too.
Straight for me as well. STOS is my 2 blade choice.
Concave Simmons for me I get them sharpe quick and they leave bigger holes more consistantly with great blood trails.LCH
I like the straight also.
Some things to consider in your choices.
Even a round head does OK on a direct broadside, but as you move away from broadside you start to see an angled impact. If the blade is narrow and somewhat pointed, a straight blade, like maybe a Zwickey No Mercy or Grizzly head, it has a certain point profile that contacts the animal and allows point on impact at very sharp angles.
It might TEND to not be deflected and enter the body more in line with its travel.
If the blade is very wide, or if it is convex or concave, more than the point might make contact with the side of the animal in a very angled shot. In some cases (I have seen this first hand) the sides of the head contact the animal before the point and cause it to deflect, skid along the side of the animal or even flip out of line. You have seen some pictures here with some broadheads "opening up the animal" for numerous inches. This is the likely reason for that to have occurred. No it won't happen all the time, but it can. If the blade hits the animal in an up/down position, there is no problem, if it hits with a flat position. . possible difficulties.
IF you get enough penetration, into the right area, well great. But if that causes the blade to skid, open up the animal, and hit further back or forward and not so deep, you have a very injured animal that looks like hell running away.
Just a thought

I just switch over to the Simmons TreeSharks. I haven't shot anything but a target with them, so I can't comment on the blood trails. What I can comment on is how they fly, and that is amazing! I was shocked that a BH so big could fly so well. Hopefully I'll be able to tell you how they work on a turkey this spring. :thumbsup:
2 blade heads are pretty simple. I can't imagine shooting enough stuff to actually see a measurable difference between straight, concave, or convex. Any tough 2 blade with a decent angle will yield predictable results. Overall width can effect hole size and penetration, but I don't see the curve, or lack of, along the edge mattering.
Simmons, concave!
Concave. Howard Hill shot concave. Is that the reason I shoot concave---Probably
The STOS heads fly real good out of my setup. They are straight edged.
Straight. Stos. Easy to sharpen. I sharpen them along with my knives using the same stone and same method of sharpening.
I also prefer straight, the tuffheads are awesome. Single bevel after reading up on Mr. Ashby. Love his research. If you get a chance and already haven't read his work it's awesome.
my zwickies start out straight then after a few years of sharpening become concave LOL
Straight much better for sharpening. Like the look of a convex and concave head though.

I have used straight blade heads for the past 20 plus years. Last year I switched to concave heads for the first time. I was able to shoot a good handful of critters and can honestly say I saw a lot more blood hit the ground than I am used to with similar straight blade hits. Pentration was also wonderful. This year I will be shootin the simmons tigershark again. The great thing about the concave heads are the increase in width you can shoot while still having a great flying head.
I have always shot 3 blade, but killed three deer this year with Simmons, 1 landshark and 2 with tiger shark and I am really impressed.

I'll shoot any good 2 blade i can get scary sharp.But i have been shooting simmons interceptors the last 3 years.
another vote for the Ace standard. Slighty rounded. Very inexpensive, sturdy and easy to get sharp. I have seen some wicked holes made by Simmons heads but they take more efffort to sharpen and cost twice a lot more
