I've switched from the Beman skinny carbon arrows to the newer Beman fat carbon arrows. These new arrows are just a few grains lighter than my old one's. But, now I'm getting some vibration on my bow?!.

Should I,

#1. Buy dampeners for my bow? I hate to add anymore gadgets

#2. Switch to heavier target points and b-heads? I shoot 100 grn. now and these new arrows seem fairly well balanced. Also, this can be very expensive.

#3. Go back to the bow shop and buy another dozen arrows that match the same weight as my old ones?

I'm sure this can't be good for my bow....

Does anyone have any other suggestions?
