Hi Scorchin - I also have the WATP tapes, and I am loving them! I bought the ones with the blue weighted balls. (Paid $29.99 on amazon.com).
It came in a 3 pack set with the 1,2, & 3 mile tape.
So far I've done the 1 & 2 mile tape and LOVE them so far. You wouldn't believe what kind of a work out you get just from using these!
Here is a link to follow, that will give you some reviews on the tapes. There is more information provided there.
