I'm still pretty new to trad & still trying match my arrows to my bows, as well.
I just ordered some 1535's for my 35# Martin Hunter. According to Stu Miller's Dynamic Spine Calculator, they should be perfect with a 125 gr. point.
But for you, Djanko, you may want to go with something a little beefier. At 29", the 1535 seems a little light, even if you drop to a 100 grain tip. An 85 grain tip puts you in the ballpark, but that's very light.
The 3555 looks to be a better choice, at least according to the DSC.
Hope that helps.
