BB Solutions, currently on fire in the US forums since someone profiles the shaft and compared it to the Ozik ( I am sure quality of materials might also play a role though)
You have to be a member to view the jpg profile - but it was the BB Solution 130 and the shaft profile is identical according to their chart. The BB is Bryant Brothers, and his company and shaft tested is here: Solution 130
This is the link that I think WB was trying to post.
