Ok Joshua. . .   another opinion. .  great. What I asked for on the post!  Sounds like you are shooting a set-up similar to mine.  That is what I found on FOC too.  I do like the extra 80 gr. and look on the Heritage. Like the cost of the ICS though.  What shall I do?  

Thanks again guys

Itd all about penetration...and 600 grains wins here...

try a  300 spine eg GT uls and a bigger point which will give you more FOC and more overall weigth Thanks Shane

Tried 300 spine GTs.  Took over 350 grains on the front end. Not good.

Dan why the prob with 350 i run about 310 on the front with about 650 total weigth out of 50@30 but man it hits hard for a girly bow Thanks Shane

Good question Shane. . .  I was just getting closer to 400 and I was still occasionally (based on release, etc) weak.  Just seemed crazy going with that much wt on an arrow to get it to work.  I would be far over 700 gr with a boulder tied to the front.  Work?  Sure.  Benefit??  Worth the wt??  Not so sure.

I suppose if I were hunting big bears or hogs at 15 yds and closer the heavy wt. and EFOC makes sense to me.  For my hunting of primarily deer species' keeping at 500-600 gr with that 18-25% FOC seems beneficial including that 20-35 yd shot if I feel up to it. I guess I see no big advantage of shooting a deer with a .375 HH, when a .280 takes them down fine while giving some trajectory advantages.        

Just my thoughts. . .

With your set up you can blow through deer with 4 blades all day long with either arrow....as long...and you don't hit the ball joint.  And there is no guarantee that any head will blow through the ball joint. Oh, and of course there's always the off side leg, but if you hit that you're gonna be eating back straps.

Like I said,....just pic one and go hunting.    

Yep both arrows are plenty heavy for penetration. I would go with the flatter shooting shaft.
