Has there been a posting yet about MOI club fitting here at Toronto Golf Forum? I'd like to read-up on what has been said AND by whom. I have read some of Tom Wishon's thoughts and opinions AND Mr. Tutleman's research, thoughts and opinions as well.

So here we go with my thoughts.
The topic of MOI comes up now and then but not sure if there are threads specific to it.
MOI is about making the club have the same heft (some call it feel) regardless of which club is in your hands. The MOI guys will tell you that there is different MOI's for woods, irons and some say wedges. So we are really talking 3 MOI values to create a set. Maybe 4 if the driver is separate?
So lets talk irons / wedges to start.
Some MOI builders will sacrifice length just to meet an MOI number and I have problems with this. Heavier heads will create a higher MOI number, so many builders will reduce the overall length to meet this number. With all the study I have done on length and lie - there is no way I will sacrifice length to create a matching heft number. To me this is building to club matching specifications, not customer correct specifications. So if we end up with a heavier head and reduce the overall length to reach this MOI then the player is now crouching to play a club that may feel the same heft wise - but have sacrificed their athletic stance to reach this arbitrary number.
The other method is of course to reduce the weight of the head. This can involve grinding, drilling, porting - or whatever it takes to drop XX grams from the head.
TLT does MOI out well and the 2 do work well together but length and lie should never be a second choice. Pulling you out of an athletic stance to meet a number should never happen. I build to MOI theories, but builder friends have double checked my methods vs the machine and there is very good correlation. MOI can get very nit picky on head weight using ferrules etc. to get very near the perfect head weight. Not saying that working to the n'th level is a bad thing as I do the same, but my methods involve progressive swing weights and dialed in lengths and lies. I find sacrificing club length to be the last thing I want to do
