I have no regrets having rails reworked, or in my case, new rails from Mark Gregory. Like RKC and the others have said, there is a lot more to good rails than a decent rebound. I'm just talking from personal experience with my Anniversary, but more than likely the OPs pocket angles, down angles are all wrong, not to mention the shelves are probably not in specs. In my case the figure 8 plate inserts required rework, the pocket casting mounting had the same issues, the cushion bevel was wrong for todays K-55 profile, and last but not least, the staple areas were toast. Some of that is probably due to years of commercial use, others maybe factory flaws. I don't know why anyone would want to correct all these issues, and then step backwards and put original 60 year old rubber back on the bevels? Makes no sense to me, even if the rubber were that much better back in those days, it's still 60 years old and there is no magic rubber out there with an effective service, or shelf life of 60 years.
There is nothing worse than playing on a table that rejects balls that were perfectly hit, and on the other side of the coin, accepts balls that it shouldn't. I don't mind playing on tight tables and missing shots, I just want equipment that meets, or exceeds BCA standards, and most importantly plays fair. Playing on a table that has crappy pockets is like playing basketball with an oversized, odd-shaped hoop, mounted to a flimsy backboard.
