I have it on 1 of my racquets since Apr, still feels tacky. Am considering to change to them completely after using up my RKEPs.
I am a big fan of Victor GR256 overgrip, it is very soft and comfy to play with so far after 3 sessions. It has this sponge bit underneath the grip that spirals round which adds to the comfort. http://www.racketsupply.com/images/products/detail/GR256.jpg
