Looks like they’re having a sale again.
5/16-14 , 12.4mm tip, 21.5mm joint. - fit my Tascarella perfectly. I own many Cf shafts. The Rhino is surprisingly the closest to my Revo in squirt and feel. No black residue that I noticed.
5/16-14, 12.4mm tip, 22mm - to fit my Schuler, I had to turn down the pilot maybe 0.5mm. Fit the Schuler perfectly. No difference in play as my other Rhino.
The low deflection is just iow for me. But the shafts play great if you can get past the sound and feel. I havent bothered to change the tip. I hear that solves a lot.
