First of all, congrats and mucho thanks for starting this site, Mr. Blake and company.
I've been slowly incubating TGM this winter. One concept that confused me was principle of the right forearm being on the same plane as the shaft at address. Conventional setups usually have the shaft pointed at one's belly button or lower, thus creating an angle between the right forearm and shaft at address. Frankly I've ignored this principle, focussing more on bent right wrist, pp#1 and 3, etc.
Then I saw Lynn's driver video lesson located in the gallery. I noticed that indeed, that his right arm and shaft are on the same plane. Grabbing my wife, we headed out to the course for 9 holes (it's unusally warm in Oregon...60 degrees) and I put his setup in motion, carding a 39.

There was immediated improvement with the driver and woods....at least 15 yards difference. Irons were well struck also but often hit left, as in dead pulls.
Which brings me to my question. My irons are 4 degree's upright, accomodating my old setup and swing. It appears that I will have to change the lie significantly....perhaps 4 degree flat??
Has anyone else had the same experience? More important, is my observation of Yoda's setup correct?
