Decided to go with the MCI's in the TS 709 MC's. My concern is that the MCI's are .370 and the Tourstage irons are .350 or .355.

What is the best way to go about installing these?

I need some advice here.

Thanks!

Bore out the hosel to .370. No other way to install the shafts properly, sanding them down to .355 will ruin them.

No it will not!

You can bore out the hoses or sand them down as you have suggested. I personally have done the latter several times with no issues. You will not destroy or ruin the shafts. I actually have seen it done on MCIs for a set of Epon 302s. No issues and it's been quite a while already.

As a general rule do not sand graphite however maybe the MCI shafts are different.

Sorry. Have to disagree. NOthing wrong as long as done carefully and with patience and a steady hand and not a machine and of course not overdone. From .370 to .355 is really not that much. Its been done many many many times to no short or long term detriment provided its done properly.

No debate here but do your research and make a decision based on information of a reliable builder. Graphite shafts are designed and built a certain way and i am tentative about doing anything that could affect this. It had been explained to me that any sanding below the paint could compromise a graphite sheet. Mjr D - I know you deal with one of the best builders and he won't guide you wrong.

I have faced the same decision before. Since I buy and sell a lot, it was tough to decide what to modify and if it would affect resale or not.

Otherwise have at it.

i'd have a problem boring the heads or sanding the shafts. once you do, you're basically stuck with the combo and will have a hard time trying different combos or even selling them if they don't work for you.

I agree. He says he has a machine that shaves the shaft down but I still think it makes more sense to adjust the hosel of the iron considering it's steel and although you're slightly, slightly altering the weight of the head, you're definitely not affecting strength or playability like you may be doing when shaving the carbon fibre of the shaft.

Machine takes off way too much. What my fitter and I do is use a hand file and slowly and patiently file down to exact fit.

A good builder boring the hosel is not an issue. It does not affect options as a simple shim will allow you to use whatever shaft you want going forward.

Cool. Grinding down the hosel rather than grind down shaft makes more sense to me.

Gary bored out the hosels when he put together my 909's and they're superb. No problem.

Yup just bore it out, don't mess with the shaft tip imo.

I have a set of Srixon blades being shafted up with MCI 120g Stiff also the Srix players CB in MCI 100 Stiff.
