I recently bought a set of Yonex V-mass Tour irons, having got on well with them quite a few sets ago. Disappointingly, the shafts - Dynamic Gold r300s - felt a bit flimsy for what are fairly weighty heads. Rather than offload a set of irons I like in every other way, I've decided to reshaft them. The problem is, nowhere on the internet can I find the required tip size. I've made several attempts to extract the information from Yonex themselves but their customer service department is very much in the same mould as TaylorMade's and Titleist's in that they haven't bothered to reply. I've also had a look at Golf Works' shaft replacement guide but it doesn't cover Yonex. It's a long shot, I know, but I'm hoping someone in the MGS community will have the answer I'm looking for.
Thanks for your time.
