Bill, I'd actually like you to see a custom clubmaker who can offer you a few demos of different length. It would be nice if he could videotape your swing as well, to check which length puts you on plane best. Then he could adjust lies and lengthen/shorten your
Pings accordingly.
If that's not an option, then I'd say that simply monitoring your game is the next best option (although I'm tempted to say that you're probably close to what you should be playing - especially if you're on plane!).
As for your wedges, I like the Rifle Spinner series (although I've heard about 'spinnerizing' other shafts). If you're using stiffs, (and they're truly stiff), I'd suggest going with Spinner 5.5's in your PW, GW, and SW (assuming you hit full swing shots with your SW), and stepping down to a 4.5 in your LW (assuming that you DON'T take full swings with a LW, and that you even carry one
)
As for the Durometers, yes, they can be bent (I've bent mine 1° weak so that my yardage gaps are better). Mike (the prez @ SMT) has setup the Duro's so that you can go PW-LW with them. More info at
http://www.smtgolf.com/wedges.asp?specs=1 Every other wedge makes for a 4° gap (where I like to start with wedges), and you can bend them, like I said, to accomodate whatever gapping you need.
The only 'knock' against the Duro's is that they've got a ton of sole. Mike designed them so that they'd be custom ground. Now, that said, I play mine as they came from the factory (no grinding). I plan on taking a little off the heel of my 59°, just so I can open it up a little more (like I need more loft for the flopper!
)
Hope it helps,
Ben
