First off is to buy a good tach PET2100DX
Try the 85 nozzle and see what your rpm is. You should be in good shape with the mods you have and about to install. You want to be in the 7150 rpm range+/-. The bigger nozzle (87mm) will give better holeshot and ecceleration (unless you spin the prop) and the 85 will give better top end if your rpm is right, this is in general, every ski is different,weather conditions etc.....TEST!
