I was thinking either the Keywin CRM Titanium which comes in at 192g/pair or the SpeedplayZero CrMo at 210g/pair. In addition the cleats for the Keywin come in quite a bit lighter over the Zeros. I can get both for close to the same price, low $100 range with the Zero slightly cheaper. Are there any thoughts between the Keywins or the Speedplays? I know a lot of guys love the Speedplays, so I'm curious to hear your reasons.
