Racetracks always make for a better looking table. Play can suffer somewhat as chip-stacks topple on the transition or a player needs to reach further because chips are kept off the track, and you cannot shuffle on a hard track, and the cupholders become chip catchers/hiders.
But since I'm not playing on this particular table, I think you did a bang-up professional job! Great work!
I've got two ideas for my left over vinyl. One that I will keep to myself until I finally build one (and of course share it here) and the second is to put a friend of mines industrial sewing machine to work in making rails for my octagon tables.
