Ed,
According to TCR 10, appendix B, there are 22,198 chips listed in TCR 10. Of those, 6,319 are roulette chips...approximately 29% of the total chips. There are 377 pages of chip listings, so totally removing the roulette listings from volume 1 would (if the current format is kept) decrease the listings by about 109 pages. Personally I'd like to see the roulette listings moved to part 2.
