Wilson Profile has to be the tackiest.
Its about 0.4mm thin, but very durable. I would say that the tack is perhaps too much. Its borderline sticky and the tread pattern makes changes grips a bit tricky.
I have found the light blue Yonex supergrap to retain its tack better than the white and to be more durable than white and black.
I'm still on, what seems like an eternal search for an overgrip that has good tack for dry hands and stays tacky in both dry or humid heat.
