I have emailed Mike and he has been very helpful. Basically I have been told that a 62" bow would be ideal but a 60" bow will work fine. I am currently shooting a 15" riser with long limbs for a 60" bow.
I like how nimble the shorter bow is and I shoot it rather well. However I am second guessing if I should get a 17" riser.
My drawlength is 28.5"-29" (realistically most often 28.5"). I have shot a few borders at 62" but it is hard to campare two different bows with quite different feels.
Bow will be used for spot and stalk, quite often in dense shrub.
