Not answering your question exactly, but related - you could consider some things:
When you "push" film, you are basically under exposing it (hence the higher shooting speed), which looses detail in the shadows (the development part of "pushing" is basically overdevelopment, although some developers do this better than others). This is what yields the high contrast, as it is difficult for developers to increase density in shadows which are basically dropped out from under exposure.
Another way to get high contrast is to expose and develop more normally and print high contrast. This way, you retain the detail in your negs in case your sensibilities change over time and you find yourself wishing you had more information in the negs.
Grain is, in some ways, a different thing - not over developing will get you smoother grain, along with other good practices, like maintaining very consistent temperatures all the way through the process, including wash and final rinse (photo flo, if you use it). Rodinal is a wonderful developer, and I might try these things before changing to something else, just my 2 cents.
I started this post a half hour ago and got interupted, hope I'm not being redundant.
