this year i put in a dalton black primary spring i cant really tell if it is better then my orange maxx perf spring i was running last year, do u guys have any ideas of what kinda performance i should expect form this new spring and do u think it is better then teh orange one form last year? 
Primary spring is a small part of the clutching equation. Are you happy with engagement rpm,s & are you turning proper rpm,s at wide open throttle.
