The only thing that matters regarding 100/125is if it affecting the spine of your arrows. And if you are shooting good, that is probably not the case. Don't fix what isn't broke.
Exactly and you working out and getting in the best cardiovascular shape that you can is going to make your hunt much more enjoyeable.. Good luck, I wouldnt change a thing if I were you. The guy here in Idaho that I respect the most as an archery elk hunter has been killing bulls and cows fro 40years and has never shot a bow over 60lbs. The last time I talked to him he had killed 48 elk with his bow. He swears by cut on contact heads and shot placement.. good luck!
