Hi Des:  I find that I have more accuracy with the 712 U than with a hybrid and I find them easy to hit.  I find them easier to hit than a standard 3 or 4 iron.  I use the clubs out of the fairway, rough and off the tee and feel they are perfect for my game…

Jim,

We do offer that Aldila RIP shaft in either the 60, 70, or 80g weight range.  Getting the RIP 80 in your fairway metal would be the same shaft, just slightly heavier.

Brendon, 

They aren't supposed to rust, assuming there isn't any damage to the plating on the iron.  I would do what you can to store them at room temperature or as close to that as possible.  They have been tested to handle all different temperatures…

That shaft can be ordered through any authorized Titleist retailer.  The weight is 74g in stiff and 77g in x-stiff.  You will need to get a quote on price from your local retail shop.

Craig,

They can be adjusted +/-2*.  We recommend you send them to Titleist to have them adjusted, so they will maintain their warranty.  This can be setup through any authorized Titleist retailer.  Let us know if you have any questions about this process…

I've read through a few articles that most amateurs can't tell a swingweight difference of less than 3 points.   D1-D5 is easy to distinguish, for instance and I have done some experiments with lead tape quite some time ago.   I can tell the difference…

The project X and the KBS Tour aren't even on the same planet as they relate to each other. The spec sheets on the computer may be similar, however these shafts don't perform the same in real world situations. 10 grams between two shafts sounds minimal…
