I tried the GripNRip. Seems like a more durable Tournagrip type OG. It's been a good decade since I used Tournagrips tho.
I think I'll bounce back and forth between the GripNRip and TruTack and be happy. I've been happy with Tru Pro overgrips and strings.
Of note, I notice Mayami, Tru Pro, Diadem, and others have their grips in near identical packaging (esp the 30 packs). I imagine they all use the same OEM/manufacturer for their overgrips?
