The Kalea 3 Spider Mini has a 10% smaller head than the Spider X. The Mid Mallet Design helps add more control to the putting stroke. The Pure Roll insert is thicker & will help to make the ball roll forward more consistently whilst adding great feel to each putt. The putter has been made with the KBS CT Tour Shaft which gives better stability when putting. The weighting system has been re-designed & optimised to get a more consistent roll & feel as well as making the putter perfectly balanced.
