I have put some thought into how the primary works on the set pin design and have come up with this. The more tension on the cam pin the lighter the primary thinks the weight is vs thinking it is heavier. I thought it to be the other way around and was judging my performance like so. For out of the hole and mid range loosening the weights seems to work for me, but now I see that it would kill top end. My question is would you rather run the weights loose and adjust to the difference with lighter gram arms or run a heavier weight adjusted by compressed tension? In my opinion I think I would rather run the weights with no tension so that you get what you get and there are no variables, but I would like to hear other peoples opinion on this.
