Honestly, unless you get a set that either doesn't have the ability to pull the derailleur far enough, or get something that's indexed only and doesn't match the indexing on your freewheel or cassette, I don't think you'll have regrets no matter which make you get. I first experienced them in 1978, and they've been favorites ever since. About 1/2 of my small fleet have them. Some Sun Tour, some Shimano.
