Seniors Golfer Colin Surman sizes up a putt using his Snug Daddy 30. Colin is currently playing in the US after a hugely successful career in the UK and Europe supported by TwoThumb Grip. Colin's game has been heavily influenced by PGA Master Professional Dr Gary Wiren who wrote the PGA Manual of Golf. "I've always been inspired as a golfer by 'the Doctor' and his teachings. I thoroughly recommend his book and the Two Thumb Putter Grip."
