My spouse is not taking to friction shifting particularly well, and I think it's inhibiting her from riding as much as she would if not daunted by the learning curve -- so I'm thinking of equipping the bike with indexed shifters and derailers (well at least the rear).
So, thinking about thumb shifters available on eBay, I'm looking at some auctions with Light Action shifters. Would they work with non-Light Action derailers, or is this another Shimano compatibility nightmare?
Any other words of wisdom about Shimano thumbshifters and derailers? Obviously I wouldn't try to mix mfgrs. but maybe there are other pitfalls I'm not aware of (such as Rapid Rise, or Ultegra not working with XT or the like).
