It mostly depends on you (how strong you are, what cadence you push), but I'd say a 12-25 will cover you for just about everything. I run a 53/40 with an 11-23, but I only use the 11 when I'm going well over 40 mph and a 40x23 won't let you go as easy up a really steep grade as a 39x25 would.

I have a 12/25 and a 12/27.
For me:
1. Which is better for a flat course? 12/23 but really any of them.
2. Which is better for a rolling course? 12/25 " " " "
3. Hilly Course? 12/27 " " " "
4. Technical? n/a
But as Gator has stated, this all really depends on what kind of cyclist you are. I stay aero for the entire time and I want to spin. But if you're an out of the saddle gear masher then the 12/27 is probably not your thing.
What is your current rear gearing and how do you like it?

Yes, a 12X25 is a good all-purpose cassette.

Just in case you ever wanted to know what your gain ratios, gear inches or MPH at a certain RPM are, here is a nice tool from the late-great Sheldon Brown:

I normally run an SRAM 12-26 cassette with a regular DA 53-39 crank

Wow... that's a really useful tool. Def. bookmarked that for future reality checking. BTW, I have an old 8-speed. The set-up is 53/39, 11-23= 11, 12, 13, 15, 17, 19, 21, 23. I think that I would like to switch to a 54 big ring, or swap the 19 for an 18, because I'm finding that the speed I want to be at isn't really matching up with a great cadence.... or, maybe I just need to get faster.

SpeedDemon. You might want to check your crank/chainrings again. Compacts are normally 50/34 (or smaller) where as a standard crank is 53/39. Just want to make sure your LBS didn't pull a fast one.
I looked to see if there was a thread which addresses this topic, and I could not find what I was looking for. I want to know what the best/ideal gearing for a triathlon would be? I know the type of course is a big factor, therefore:
Which is better for a flat, fast course?
Which is better for a fast rolling hills course?
Hilly course??
technical??
or any course I neglected to mention...
I am looking for a rear cluster for my disk wheel and wold like to know the ideal one to get. I have a FSA carbon compact 53/39 on the front.
Thanks!
