To answer two questions at once. Indexed shifting a triple is more trouble than its worth. It will need more adjustments and offer less trim finesse. So, skip the indexing and the ramped rings. I run friction shifters and good, but no name LBS silver unpinned rings( 48/34/26) on a DaVinci triple crank and it shifts fine. The only time I ever have a problem is when I have waited too long to drop into the granny.
About the gearing. I am considering switching one of bikes (Rambouillet) from a triple to a 44/30 double with an 11x28, 9 spd cassette. This will give the same top gear as my 48x12 and only one gear less on the bottom 30x28 instead of 26x27. One downside I can see to this is that the 11 will probably wear out pretty quickly. If that does happen I think I will move the cassette to a bike with a triple and lock out the 11. Also, the jumps - 12-14-16 - are a little bigger than the 12x27 spacing - 12,13,14,15,17. The only objection I have to triples is the extra work cleaning them. I ride a lot of dirt roads and tired of pulling the whole thing apart (especially the XD with the hidden bolt) to clean the middle ring.
