I have the 913d2, and love the Diamana 62 in it. I feel it is slightly stiffer, and gives me good control.
But, when I had a similar problem, I changed from the 10 finger grip to the overlap and it radically improved by driving.
I went to a 913d2 and the fitter helped me configure it. Great choice. I get a much more consistent flight. I've no readjusted my 910H's to similar configs. A lot easier than my old TM w/ the weighting system, which was a PITA to change.
I recently purchased by 2nd Scotty (Futura X). I also have the older Futura. I think it is a great putter and an improvement. But if you aren't sure about a Scotty, check out the Bettinardis. They are great as well. But I've had some solid less expensive options. But to me, you can feel the difference b/w a cheaper putter and a Scotty, Bettinardi, or any other premium putter.
I've been doing it a long time ago. Back when, before every putter had a headcover, someone told me that was the best way of keeping it safe. I don't always put the covers back on during a round (helps cut down on losing them), though I usually try and put the putter cover back on.
Very few things hit like a Bettinardi, or a Cameron. They are 300-500 for a reason. But, the best feeling putter I had not in those categories is my Cleveland classic. They come in several styles, and have a great feel for under $100. I feel they are the best putter outside of the elite priced Bettinardi or Cameron. I have the Cleveland Classic 7. Also, some of the older Bettinardi's like the Ben Hogan Baby Ben have a pretty good feel, though a mallet not a blade....
Yeah, I think I carry a lot of wedges at 4 (though I often drop to 3). I usually carry a 47, 50, 54, and 60. I feel that covers everything. You could review the bounces you've selected for your wedges, and I bet that would allow you to cut 2. I think the extra 4w would be great, and certainly the money iron (7i). In fact, I think my 7i is my most versatile club. Can pitch, run, vary it from 100-160.
The 4w can be helpful around the green, as you can use it to run...
I play the e5 and e6s. I feel they are a great ball for the price. I rely on my short game, and feel I have a great feel with either ball, though the e5 is better.
I'm going to give the Titleist Velocity a swing my next time out. I prefer to stay in the 25-28/box range. I think bridgestone makes a great ball for the price.
