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.
