C1 worked good but I did end up going with B2 after a bit of riding, its all personal preference and how you ride imo, and I did take the advice of other members here and used the pennies to figure out what I wanted for weights and was able to find 14 g weights from the can am guy. They were very hard to find at the time like everything else. They seemed to grab a little quicker than I thought they should so I drilled the center slightly on all evenly using a digital gram scale. Comes down to trying different setup’s to see what you personally are happy with. Pretty sure my final weight was 12.75g, it was a while ago, it’s in one of the threads, good luck with the new machine
