Frontline Cero

The Frontline Cero is a mallet built around a design idea that Pluggedingolf.com describes as moving the center of gravity forward to reduce gear effect on off-center putts. That publication reports tungsten weights totaling 47.3 grams set into the toe and heel, working alongside a milled aluminum face insert Cleveland calls SOFT, or Speed Optimized Face Technology, which the outlet says is meant to help eliminate putts left short. The finish is matte black, and Pluggedingolf.com notes a black shaft to match, along with a stock Lamkin grip in an oblong, slightly oversized pistol shape with a soft, grippy texture.

On alignment, Pluggedingolf.com describes one sight line centered on the top line flanked by two more sight lines on either side of the flange, and reports that the sole lays perfectly flat, so the heel and toe sit level and the face is easy to square up. That flat lie is one of the traits Community opinion singles out for praise, alongside the black shaft and a feel and sound off the face described as solid and smooth. Pluggedingolf.com's own reaction leaned favorable on sound and sensation, calling the strike a soft, muted tock and writing that it's a pleasant sensation that makes you want to hit putt after putt.

Not every reaction was uniformly positive. Community opinion on the Cero also included a complaint that, set against other high MOI putters, testers did not notice added speed per stroke effort, a point worth weighing against the forward-CG, gear-reduction case Cleveland and Pluggedingolf.com make for the design.
