Spammage: Honestly just depends on what suits you.
Huge part of of it.
The L70 Versa is a great little putter. Personally I was not over keen on the L96 one, finding it more of a ding putter (not overly my style. For want of a change much as anything I bought the L94 Nike.
Personally I can't recommend the Nike too much. Yes it has that extra bit of precision, but it's lesser balance means weighting putts with meter set deep is sub optimal. I am still (lol) waiting for a L70 Versa (blade style) based putter upgrade with an extra half dot precision, or maybe a Nike with a bit more balance would do it fine as well.
Nike seem to have the march at the moment ?, and so a little surprised they are happy with that L94 being as it is. Maybe I will get my wish:)
Free rental soon maybe (Masters). Decide on your style, rent a couple, make a decision then stick with that until you know it inside out. Not saying you need to change btw as only you can decide that.
Good luck.
