Can you tell the difference between a 180 gr. broadhead with a 20 gr. insert vs. an arrow with a 100 gr. insert and a 100 gr. broadhead?
I wondered if anyone noticed any "planing" with using a lightweight broadhead. I currently use a 100 gr. brass insert, and want to try a 100 gr. Magnus Buzzcut to give me 200 gr. up front - but I'm worried I will notice "planing" and not achieving my desired arrow flight with my weight not in the head.
Any insight is appreciated!
Thanks,
Alex
I have shot a lot of different combinations and never noticed any variation in arrow flight. I think weight is weight.

you'd have to be a superb shot.
I know I couldn't tell any difference.
I have noticed that I get more broken arrows when i use a heavier BH and a light grain insert. like your exapmle of 180 Bh and a 20 grain insert. it seems to me that the 100 grain insert and 100 grain bh is a tougher combo.
if i happen to hit bone ive had the arrow break right behind the insert a few times. .. or a rock in the back yard :)
Split the difference...150g Magnus & a 50g insert.
There comes a point where adding weight farther and farther back does show up different.
If, for example, I put a 200 gr point on a 50 gr insert and it flies perfectly, and then I substitute 2 50gr weights in tandem behind the insert and reduce the point to 100 gr, there is a definite shift toward stiff.
I think this is a somewhat extreme example, though.
Alex,
From what I've seen (if comparing a broadhead of similar lengths/widths) you may soften your spine with the 180gr tip.
It's very minimal though.
If tuned properly, a 100gr insert and a 100gr magnus will fly great. I've used a 100gr insert with a 125gr stinger with great results.
For example,
I was playing around with two setups at the start of the year, one with a 125gr tip and a 150gr insert and a 200gr tip with a 75gr insert. To get them to shoot bullet holes, the 200gr tip arrow was 1/2" longer (throat of nock to end of insert). With the field points screwed in, they were only 1/4" in difference.
In my opinion, even though the total weight up front is equal, having the weight positioned more forward will soften spine.
Again, minimal though.
I'll bet there is a slight difference, but I'll also bet 99.9% of everyone who shoots a bow could not tell the difference.

Personally, I haven't tried it but a lot of fans of EFOC are now acheiving it by double inserting a shaft that should be on the weak side for their set-up, but claiming that the depth of the inserts act just like a footing and stiffen the shafts, allowing even more weight to by loaded up on the end.
The farther the bulk of the weight is forward, the more effect it will have.
It`s similar to cutting carbon shafts. When you make a carbon shaft shorter, it gets stiffer. Even cutting 1/4" can have drastic effects on spine.
Moving a percentage of the weight back into the shaft will increase the spine.
