Rossa putters has introduced a new Mid length version of its popular mallet-style Monza putter. There's more to making a long and mid-length putter than sticking a standard putterhead on the end of a long shaft and the dynamics of both the shaft and stroke call for a putterhead made larger to precise proportions, and heavier to the exact degree. Careful analysis by Rossa engineers resulted in Monza heads created to deliver optimum performance with the longer shafts. The Monza Mid is 11% larger and weighs 30 grams more than the standard Monza. The larger size and added weight contribute to a higher MOI, equalling greater stability and forgiveness on mis-hits.
