Yep. Great thing about golf is it lets you use your imagination. I figure I have all these wedges so I might as well use them. I learned the game when I didn't even own a sand wedge - did my fringe chipping with a 7I. Tom Watson still doesn't carry a LW, and there's never been anything wrong with his wedge play.
Then why does Tom put his name on these? Another great athlete shilling something he doesn't use. My dreams are shattered.
Just because he endorses it, doesn't mean that he uses every loft in the line. Last I read he used a 56° as his highest loft. A few years ago I believe that it 54°. His wedge setup for the 2009 Open Championship was Adams Puglielli (52°), Tom Watson (56°). When he won the 2011 Senior PGA Championship it was Adams Pugielli Wedges - 52° and 56°.
