I shoot the exact setup as Elknut (I must be doing something right!?!? ). I agree totally that 100's vs 125's really doesn't matter. The shot and confidence in making that kill shot means more than 25 gr. One thing I noticed with picking 100's or 125's is your arrow length. 100 vs 125 might be throwing off Front of Center % and affecting arrow flight. Also, 26 days and counting for Elk hunting in Utah!
