I have tried lots of overgrips. Much as I love Prince, I have found their grips to either be a bit papery or too thick and rubbery that theyre actually awkward to wrap.
The closest to Wilson Pro is Supergrap. But I would say the feel from SG varies with colour. White seems to be best colour and the most durable, second would be the pale blue.
Tourna Tac is different to WP. It seems a bit thicker and has a stickier type of tack to it, certainly not for everyone as other threads have covered. Although saying that it sucks I would think is good if someone is looking for good absorption qualities.
