You should invest in some supertips wieghts. I would think you should start around 65 grams IIRC. I am using the Cat green secondary spring with shockwave helix. Can't remeber the primary colors though

Beleive it or not I have had the best results with the stock weights.

Try this:
Stock weights with 4.5 grams in each hole
14.5 rollers
B-B-B primary spring
Pink secondary at 90
stock helix

If you over rev get some brass rivets from MPI.

Supercharger weights

we install 8BU-00 loaded but for super at high alt. would lighter.
Small rollers 14.5mm
Blue/Pink /Blue primary
secondary EPI Purpler cat spring
Shockwave or straight 50 helix
0-2 cat spring
