Query: The light blue grip that does not slip...

I tried the white tacky grips from other companies and they are great in the winter with 10% humidity, but when the summertime rolls around in the Ohio valley there is nothing I've found that beats Tourna Grip. I play four to five times per week and change my grips about every ten days or so. This grip is rough instead of tacky but I've never had any problems with blisters as I've seen with other reviews around the web. I use Tourna Grip year 'round now.
