FWIW, I upgraded from the L33 to the L70 Versa. Honestly, I think it was a step backwards. The L70 version is deadly accurate, no doubt about it...but the earlier version, and even the 2 dot forgiveness Rossa, is far more forgiving on slight ding misses. With the L70, a missed ding outside 8 feet basically means a missed putt.
Now that I've got the L77 Method as well, I think I'll end up using both. I hole more mid/long range putts with the Versa(better accuracy), but I miss lots of short birdie putts with it. Conversely, with the Method(more forgiveness) - I'm deadly inside 12 feet, but hole fewer long putts.
