Hey all, just thought I would share a quick tip and trick I discovered from hitting off of mats last summer. I noticed that when I hit off of mats in the drizzling rain that I didn't get any of that green plastic mess on the bottom of my club, so I thought why not just put a bit of water on the mat when it is sunny. Sure enough, an ounce or two of water put on the range mat (where you strike) will prevent the plastic from adhering to your iron soles!
Another thing I discovered. Prius floor mats make superb hitting surfaces. They have rubber spikes on the bottom to keep the mat from moving on the turf, mat, soil etc, and the synthetic material doesn't stick to your club or scratch them. You can also see where your divots are!
