What would the result be?

I have always shot 125 gr. Thunderheads. I used to shoot an Onieda Eagle and I was pulling 63lbs.
I am currently shooting a martin and pulling 63lbs. After I got the new bow I switched to carbon arrows, but I kept the same 125gr. Thunderheads. (I figured I'd just use what I had)
I need to buy some more broadheads and I was wondering what would happen if I switched to the 100gr.? Does anybody know what is recommended? I could stop at a sport shop and ask, but I thought I'd ask you guys first.

Your FOC balance point will be further back, and your arrows will likely gain about 6-9 FPS. Don't be allured by the speed though.... shoot what shoots best.

Best advice in your situation... buy a package of 100gr field points and shoot them a bit alongside your 125s... you'll be able to see which shoots best pretty quick and easy. Its a cheap investment compared to buying and testing broadheads.

Before buying broadheads I'd try to retune with 100gr fieldtips and see what the results are. I doubt you'd get 6-9 fps increase, but 5 fps is more like it.

100 grains should be plenty of foc with that setup if tuned properly

Im going to lean you towards a 100gr BH. These should work best out of your bow and your arrow setup.

Thanks for the help guys I'll grab some field tips tomorrow.

Tips wont tell the story, apples and oranges unless the martin is that much different than a Hoyt. Other than the bow and we're different I've done it. You may notice a slight rise in impact point is about all that will happen. Make the rear end lighter and you might not even notice that. Those heads do a lot of steering. I'd go with the 100's unless I had the 125's. 100's aren't 100 anyways 106. 125's are 128. Shot'm if ya got'm.

That's my .02 You my find I'm way off but like I said, I've done it. If I changed I'd try something different like a Magnus. You might be able to find some used 100's.
