Odi's take longer to break in, but when they are broken in they are the best. Obviously you dont want a grip to be too grippy otherwise you can't do scooterflips and such. But edwins are like too grippy for me, and i have the sweatiest hands around. So ODI's if you want cheap, longlasting, soft grips that i litteraly havent worn down in over a year; edwin's if you want a grippier softer grip.
Nuff said.
