I experimented on one action by replacing #'s 1 & 88 capstans. It dropped the friction by 3 grams and since this action did not have a friction issue I did not see the benefit to the extra work involved replacing the set. Their weight difference as translated thru KR only affects DW about 2 grams. So unless there are weight and friction issues and you need to squeeze every gram out that you can, I don't see them as a cost effective replacement. -- Regards, Jon Page
