25NL: BVB PFR-size

[Vecernicek]

This may sound stupid, but I'd appreciate an answer to both questions.

#1) When folded to you in the small blind at .25NL, what is the optimal standard raise?

#2) More specific: my stupid slide bar on Ongame sites jumps from .50 to 1.00 (and it's very annoying for me to type in the right number). So, if you had to choose between making it .65 to go, and 1.15 to go, which would you choose (they both seem wrong to me)
