I find the 25t isnt too bad up there but there are a few pinches where you wish you had a few more teeth to help out! I definitely wont be trying the Mt Glorious Rd (Pei Rd) climb up from Samford with my current combo!
I run standard cranks up the back of Coot-tha, and have put on an 12-28 Cassette (originally had a n 11-25). I actually find the standard crank better than when I was running a compact on my old bike, especially where the road flattens out a bit in a few sections. (The first hairpin for example). You can spin it up quiet a few km/h without changing gears and thus loosing momentary momentum. Can get it up to around 18/km/h whereas on a compact you are tempted to stay in the easier gear and just spin that gear - even though it feels easier on the legs you are going slower.
Have also found the 12-28 is much better than the 12-27 up there, as the jump from 24-27 is big and ruins a consistent cadence.
