Putting biomechanics expert Dr Paul Hurrion has collaborated with Gel on a range of putters for the second time. The Rego mallet putter with a centre shaft is part of the Paul Hurrion Signature Range and comes with a multi-layer grooved aluminium insert. GEL's grooves are designed to give the ball that allimportant forward roll from impact, thereby eliminating skidding and increasing the control golfers have over their putts.
