I fought this same thing two years ago. I have a similar set up as you but with 29in arrows and I am right on the bubble for spine. For some reason Axis 340’s couldn’t handle the 125’s and my rampages did alright, so I dropped down to 100gr heads and that made a noticeable difference. I also walked back tuned my bow last year and that got me right in the money! Try shooting 100 and 125 field points about as far out as you still feel you can accurately shoot. Whichever one shoots tighter is the weight your spine of arrows likes.
