Ok, I've got more of the info in front of me now. The clubs I hit on the monitor were my TM R7TP 7iron. 35 degree Dynamic Gold Stiff, 36.75". The Mizuno JPX 900 Forged was a 6 iron. 27 degree 37.25" Modus 105 stiff. The Ping I200 was a 7 iron. 33 degrees and 37" AWT 2.0 stiff.
My R7TP was consistently shortest, carrying on average 140. Ball speed average was around 102
Ping I200 was flying at a higher trajectory than my old one and carrying consistently 145-155. Ball speed was as high as 110 and I think the average was 105.
the JPX 6 iron in the first shaft (don't remember what it was) I wasn't getting as high a ball flight. When we moved to the Modus, it had the same flight as the Ping. Depending on how hard I swung, I was getting carry up into the 180s. Average at my normal swing was 160-170.
I asked about regular shaft and he felt that my swing speed was still very much at a stiff shaft speed.
I'm not in a big hurry so I'm hoping to be able to get into some more places and try some more irons though I could fall in love with either of these I think.
Yes, trying to find something used would be great. That's how I got my R7TPs (demos). Buying clubs off of Ebay isn't like it was 10 years ago. Now a good number of them are clones from China that a person wouldn't know is a clone until you try contacting the company for a warranty issue. Again, I'm going to be very choosey and make sure I'm making the best choice for my game. Once I decide what I want, I hope to be able to find a good condition experienced set.
