The three things to consider when choosing a broad head are how the weight will effect the spine, how it will effect the FOC and what the cutting diameter will be.

The lighter the head the stiffer the arrow will be, the less FOC you will have and normally you will have less cutting diameter. I really wouldn't suggest heads lighter than 100 grns to anyone unless they were shooting a very light set up. Like a short draw length with short light arrows. The smaller cutting diameter will help slightly with penetration issues. Say for women and kids or really small guys like myself.

If you are shooting more that 26 inches of draw length and more than 50 lbs of draw weight I would suggest you look at broad heads in the 100-125 grn weight range, maybe heavier in some cases.

My opinions anyway.

I shoot 140's & 125's on hogs, and 100's for everything else

Obviously you proshop dude is a speed freak. LOL As was mentioned, what weight head depends a lot on the arrow you shoot, poundage, draw length etc. We'd need to know those things before we could say what's best for you.

100 all the way!

Choose a spine that will handle a 125 head and enjoy the extra FOC. The speed difference in a 125 grain to 85 grain head would be only 10fps or so. Hardly earth shattering. You can still arrive at a lighter arrow by choosing your shafts accordingly. I do shoot some of my arrows with 100 grain heads, but generally those have weighted inserts.

125 grain thunder heads real nice and work well with my setup
