ahha....don't be so sure of the brand sizes being consistent though
different shafts vary the size of alloy walls on the shaft. My kpro diamond is really tight on my proton power but my kpro wirefade is a tad bit loose (hardly noticable)
95% of shafts imho fit together with heads fine from the manufacturer. you shouldn't have any problems. Glad to see you on the forum and hope to see you posting around....
