MOI Matching Club Fitting

[dee cee]

Good stuff Daves. Keep at it.

It has definitely made them easier to hit for
me, especially the longer clubs. It also makes switching between sets very easy, pretty much irrespective of shaft, grips etc.

I am pretty sure that's actually the whole idea. So its good that is what you have experienced what I have only 'read in the brochure'

I converted another set this morning, the Ping i20s. I had built these to MOI using SW advancement i.e. 1.3 SWs per inch. This was before I bought the Analyser, and I hadn't actually got around to checking them. I was pleasantly surprised to find that they were pretty much within tolerances, and not that far away from my MOI target.

How was the Ping head weights, exactly on 7 gram increments?

I can't say for sure because I don't seem to still have the data from the original build. But my MOI build data tells me that the club weight progression was pretty much spot on 7 grams per step. The shafts are R400s, so constant weight shafts.

I might have mention this in another thread recently, but I got a new friend who knows a little bit about Pings production, and we were talking about the head weights, He said that all the irons now have plastic inserts, and they are made with varying weights. So once the head is finished,they add the exact plastic weight insert needed to get the head precisely to spec.

Yeah it's called a CTP, custom tuning port, and has been around for a while.

Is that the decal in the cavity?

Some more grist.....

I recently MOI matched a set of 716 AP2 irons with TT DG AWT (Ascending Weight) shafts. When I measured their starting specs, the SW were pretty much spot on at D3 through the set (1/4" overs), and the MOI spread were pretty closely grouped. Much closer than I normally find for a conventionally SW constructed set. The 3 gram progression was close to getting the set to MOI matching. There was less than a 2% spread from high (4i) to low (PW). I aim to have well less than a 1% variance when I build, but 1% is considered OK. If the AWTs were 4 to 5 gram progressions I reckon they would be pretty much spot on. It meant that I extended each club by very similar amounts to get my MOI target matches.

anyone in Sydney with MOI machine?
