I haven't tried the L92 Spider yet (1 more level to go), but I rented the Max putter and the L77 Nike during the free rental weekend and didn't like either of them. I rely a lot on the 5 foot movements (I believe it's 6 feet for males), and with the lower increments of the higher level putters, those movements weren't consistent with the Rossa's... they weren't 5 foot movements. I would assume that the 92 Spider does not have a similar issue since the increments are similar to what I use now, and the club itself is not as new as the Max putters.
I'm sure it's just something you'd need to get used to for longer than a free rental weekend, and if you don't rely on the movement at all, it's not an issue. The increments of the Max would sway me in that direction if it weren't for the movement differences.
