Happy New Year Pasatiempo and everyone else!
I'm a member of an Alister McKenzie course here in Britain---the greens are hell, with vicious slopes, but otherwise it's OK.
I've been playing golf for nearly 60 years and have always played with blades, because they were the only irons available in the 1950s, but I have tried cavity backs. These always go very well for a short time, but are so forgiving that in a very short time, I start mis-hitting them as there is no real "feed-back". I return to my blades and instantly get feed back and this automatically improves my striking. I have therefore dumped the cavity backs I experimented with, despite now being 71.
If I were you, I'd certainly go to blades, but get them with plenty of "bounce" in the soles----I use Ben Hogan Apex blades (with 4 (stiff) shafts for this reason---they have a lot of "bounce", and in consequence do not have to be hit absolutely perfectly to get a good strike. Blades with little or no bounce are extremely difficult to hit well, even for those with a shallow angle of attack.
The Nike VR blades also have very good "bounce".
David Graham designed for McGregor for years when they still made superb irons, and he maintained that ALL irons should have plenty of bounce. He (and I agree) felt that this is really the most important aspect of any iron, as you can hit down with confidence, without fear of "digging". Indeed, it is possible to hit slightly "fat" shots, and the club will bounce and take the ball with it, without loss of power. Try it--you'll never look back. Good golfing in 2013!!
