I went back to make sure and I didn't see anywhere that the OP said he was going to dump his OCR. He is going N+1 as I read it and most bikes he wants to ride seem to be sans triples. If he already has a triple and the N+1 bug hits why not go with the double? If he ever got the bug for electric shifting would any of us say, don't do it till they come with a triple? I say go for it, take a walk on the wild side, by a shirt other than white and a suit other than black and eat ice-cream other than Vanilla.
