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.

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.
