The 15/43, as you suggested, might be over revving the engine. That gear ratio would be somewhere around 2.867, which is almost as much a difference in the high rev direction as the 16T is in the lower rev direction. I think that would rev limit the top end, instead of gear limit it. You're right. ....I'm just kind of rambling.
....
I just finished doing some math and I get the feeling that it might be a "better" overall gearing change to do the 15/40 (2.66) than the common 16T swap (2.56). It would, however, cost more money and wouldn't be as simple to install and you'd only want to do it if you haven't already done the 16T swap.
I think I've decided on the 16/42 (2.625). It's right in the middle.
