RE: 100 grain vs 125 grain
Let me have a stab at your delema.... If I understand your question correctly then this would be my answer.....If your Bow is shooting @ 275 fps and you are using a 375gr.totalwt arrow your ke would be 62.98 lbs...now changing to a lighter arrow { by 25 gr.} and your speed increased by only 10 fps. your ke would also increase to 63.14 lbs. so I would think that it would be in your best interest to change to the lighter arrow...this does not sound like a lot but when you are at the breaking point of using mechanical versafixed blade it makes all the differance....Every little bit helps right....[:-][:-][:-]
