club glove towel is the best. I love it because it holds water better and doesn't dry out as fast. It is also good because it has a waffle design that gets in the grooves a lot better then a regular towel. If you have money, get it. If you don't, just get an old towel you already own.
Club Glove towel is the way to go, you don't even need a scrubber to clean the grooves.
