Thanks all!

I should have mentioned that my setup is all Shimano. I don't even know what SRAM looks like...lol!

I am not planning to change to a compact double up front since that would be a much more significant change. I just want to keep my triple and see what I can do in the back. I'll take it by the LBS and see what they have to say. Even one more low gear would be helpful, but if I could get the 30 without changing the rear derailleur, I'd do that in a minute. I can probably live without a 32 or 34 in back as I do have a mountain bike and Bike Friday with mountain gearing in back, so I can always ride one of those bikes if I think I'll be climbing huge mountains.

As it is now, I feel like I run out of gears on the middle ring quicker than I'd like, and I hate having to go to my granny chainring. If I had one more gear to shift to, I could stay in the middle ring more and only rarely have to go to my granny on my road bike, which is mostly what I'm looking for. And yes, occasionally I would like one more gear even in my granny chainring on that bike, but not often.

I'll let you know how it turns out!
