Avoid the greenside bunkers at all costs. If you end up in one, strongly consider playing at the center of the green instead of at the flag. And by strongly consider, I mean do that unless you're 100% sure you can pull off the shot without ending in another greenside bunker.
This is pretty much what all teaching is based on. The idea that changes in your alignments will make you a better player.
If a player comes in with either too strong or two weak a grip or a flying right elbow or a flat swing or an upright swing, the average teacher wants too change it.
I too believe there is certain things you can do to change your swing. But I more importantly believe that a proper transition fixes a lot of little details.
I think most people would agree that tiger, jack, Sam Snead, Ben hogan, lee Trevino, and nick faldo are some of the best ball strikers and best winners of all time.
But Trevino had a really strong grip and hogan had a really weak one. So any where in between will work.
Hogan had a really tucked elbow and jack had a flying elbow. So anywhere in between will work.
Sam Snead had a pretty upright swing as did jack and tiger but hogan and Trevino both much flatter. So anywhere inbetween will work.
All these players do have one thing in common and that is a similar lower bodie transition
The original Apex blades are nice however, in terms of usability and appearance, the '73 - '78 Apex blades are much more coveted. The "Holy Grail" of ALL Hogan forged blades are the initial "Precision" irons made in late '53 - early '54. Check the prices on eBay for confirmation.
