Hey Jack -
Just rec'd my Pro One 18x20 today. Man these are high quality frames. I'll have a chance to hit with it tomorrow; playing in the afternoon with the GF and then tomorrow evening at Oak Brook for some dubs.
Gotta love TW as well. Bought this as a used "B" grade frame, but this thing couldn't have been hit with for more than 1hr; not even a scuff on the bumper. It's also fairly freshly strung with TF NRG2 17g. I was setting up the stringer as UPS came to the door, but looks like I should be able to test it with the strings already in the frame.
Hope we'll get a chance to hit sometime!
