I stick to ~ 400g , much lighter feels like a wafer to me. Have been experimenting this year, between mallet- Yes sandy 12, Nickent Omen Prophecy #4 (backweighted and longer length), and blade Maltby Pure Track PTM (~ 386g). Feels light to me but it's the flavor of this week. Also messung with grip. Can't quite get comfortable with that traditional overlap of two fingers. 10 fingers with thumbs down the handle feels the best to me....speed control and long putting is much more consistent, but I'm working on directional control.
