I don't understand why they felt the need for EIGHT different textured tapes, but whatever - it's their company.
That being said, I am currently trying the purple tape (second strongest) and I like it so far. I like it even better than the Real Bowlers Tape silver, which I find gets dirty really quickly and tends to roll down a bit, necessitating replacement pieces all the time.
Now that I use IT thumbs I don't change my thumb tape as quickly so I expect this to last a while.
