Question for club/shaft gurus?

[ManchesterGolfer]

I want to put some project X shafts into my Callaway X tours. I have seen a set of .370 par tip are these the right ones? Also I have a GBBII Pro Series that I'm thinking of reshafting (bored waiting for the FT-i to come out and I've got to Ho something) what tip size is this one?

cheers MG.

The X-tours are .355.

The GBBII is .350, but you can (and have to) buy adaptors to accomodate a .335 shaft, but it's very easy. Golfsmith sell the adaptors for like $2.
