Odyssey Versa #1 Black Putter (L70+). Love it, I highly recommend it.
After going thru levels all the way up to 70 with the wgt starter putter, the Versa L70+ is a dream compared to that. (tried the TM Spider L35 but found it awful for my style of play).
The starter putter is very consistent on length / distance but does scatter left to right a lot.
eg see "wgt putter comparison, accuracy and precision" www.wgt.com/forums/t/559073.aspx
(the detail for that came from a massively long post chain called Putter precision tests - Now with irons! ... www.wgt.com/forums/t/195080.aspx )
