Looking for opinions on primary and secondary springs for the MY22 850 XCR. The sled is out of breakin mode and currently has slp magnum adjustables in it. What is everyone liking for spring and weights setup. I'm not interested in a helix or gearing change right now.

Are you close to 100 in 660?Here you go......and use the spring cup with it......saves over 35 grams of weight also. I have my clutches balanced and lightened by Patrick Custom Carbon. Spring cup, roller bearing, slippery washer in the primary and titanium pins in the primary. I can use 74 or 76 gram belly busters depending on what helix I am using and spin 8200 all day. I also have a pair of the magnet weights that I have had up to 78 grams that have a totally different pull. Still trying to get it down to 8050 consistently. Black/Green secondary with the stock helix works good....with my full progressive helix I have to use a 155/222 spring to pull it. I have tried several primary springs from 120/300, 120/310, 120/320, 125/340, 140/320, 140/330, 150/290. Alot of data with the Dragy to see what works and what does not. I still need to try more combos. Believe it or not, one of the fastest times I made was with the 120/300, 74 weights, stock helix with Black/Green secondary spring.
