Trudat & JCfuncklive.....Sam T, Noobie, and Stagday are all correct. About the only thing I could add is that with a bore-thru head not only will the shaft play stiffer the torque will go down a little as well. There is no doubt that the 757 is much more popular because the pro’s play it. But of course they have a pro swing. The 757 is a low-ball flight shaft that is harder to load (or get the most performance out of the shaft) then most shafts. The 652 is the "everyman’s" Speeder that can also handle a hard swing...it is the best of both worlds unless you are a natural hard swinger you may want to stick with the 757.

The 652 is harder to find on EBay because it is not as popular as the 757...but have you ever noticed how many 757 there on EBay? I believe that is because a lot of people buy the shaft and then figure out that you better have a fast swing to load it. I have a 652 in an R5. I got mine on EBay. I was out on EBay looking just for the shaft and found one for $118.00 new. Normally a new 652...and most other speeders... start at $230.00 The reason I did not buy the shaft was because I found my R5 with a new 652 already in it for $276.00 on EBay. I bought it in a second because I wanted a new R5 anyway. The club head was not new but the shaft was. So you can find just about any kind of Speeder on EBay for great prices but you may just have to hunt and wait for a while. I have even have found 660TR Speeders on EBay, which are very hard to find even from a dealer because they are usually only sold in Japan.

A pull is easy to find on EBay too but be careful with a pull (used shaft that was pulled from another club). Most pulled Speeder’s are ok because Speeder’s are a rugged shaft that can take a beating. What you have to be careful about is if they have been tipped. When you tip a shaft you cut some length off the tip to make it play stiffer than what it is rated. For instance you have a stiff shaft and you want a stiff and a half shaft…but not quite an X flex. You can tip the shaft and play between flexes or jump a flex and just have a shorter shaft. If the shaft has been tipped most on EBay will say how much length has been cut off but you will not really know what flex it plays. Also if the pull came from a non-bore thru club head it will not work in a bore-thru club head because the shaft will be too short.

I hope this helps.
