Curves and their sources
I'm not a "curve drawer" (what an awful phrase) but I'm pretty sure I've read, both recently and in past, that the basic curve one gets is generally somewhat more a property of the film than the developer, though both contribute.

This about sums up my experience as well. In fact, TMX and Xtol has become my standard when I want nice smooth toned 16x20s from 35mm. I can't get grain that small (or the appearence thereof) even from Pan F+.

I use it 1:1 and have never had the failure mode that has been reported, even in half-full bottles after months. Maybe I've just been lucky.
God I love these forums. I'm gonna use this one.

However, I too am switching "back" to D76 as my standard developer, because due to life's press I am shooting film less frequently and thus developing sessions are intermittent. I can mix D76H (HQ-less variant, bit more metol) cheap as sand from dry chemicals to get a fresh liter at a time.
I think that TMY looks better in D76 than in any other developer--but I'm just one guy.
In short, yes. Both film and developer contribute. Film has an inherent curve, and developer will bend it a little more this way or that way.

Using film since before it was hip.

You answered your own question in the post Bruce. Start with what you know the best - D76. I strongly recommend only changing one variable in ones photography at a time as this keeps things from getting away from you. After you see what this produces then take it to the next step with the experience in your back pocket. My money is that you stay the course with D76 as it is easy to mix and cheap and is foolproof. But you already know that.
