I put a Zan Hybrid Max on my Jacoby Ultra Pro. 12.5 .
I really hated the shaft when I got it about 6 months ago
I quit playing with it.
I was ready to put it up for sale and a friend of mine said to try that Zan HM out.
figured a new tip would help in my sale.
I cant believe how this tip changed the shaft .
I have played Sniper,kamui,and everest.
there is no right tip, but I got Lucky and it works very good with that shaft.
This tip is worth the money.. $28 a tip J/S
Good Luck with your choice.....
