Finally, I have had a full set of TaylorMade P770 irons out on the course for the last few weeks. The P770 takes a bunch of DNA from the larger P790 and packs it into a smaller size. Don't be fooled, the smaller size still gives you a bunch of distance and forgiveness! SuperStroke's Wrist Lock putter grip is designed to help add stability and consistency to your putting stroke. It really does give you the feeling that the putter is locked into your stroke and won't go anywhere.
