When you switched from alum to carbon you lost quite a bit of weight (possibly up to 100 grs or more). Then you lost more weight going to the lighter BH. What you gained in speed, you lost in kenetic energy. You can gain some of the weight back by going back to the 125 gr BH but you have to be careful with your arrows. But in your case I would think that the 25 gr will not underspine your arrows. Especially at 29". My arrow/BH of choice out of my Martin Cheetah set at 57 lb is a Carbon Impact 5000 and 100 gr Magnus Stinger 4-blade. Out of my 62 lb Firecat I shoot 5575 Gold Tips and 125 gr Magnus Stinger 2 or 4 blade. Another good choice is the Muzzy Phanthom. The only problem I have with these is they have a tendancy for the main blade to come off when you pull them from a BH target. But I have found that they fly identical to the Stingers.
