I *love* this film. It's not truly *insensitive* to red, just has reduced red sensitivity, which results in some interesting tones; I haven't felt the need to shoot it at reduced speed for that reason, but I suppose one could. Blue skies do tend to blow out, however, and overexposing will make that worse---I would suggest a yellow filter for shooting in full daylight, same as for ortho film.
Checking the MDC, I find that it suggests 7 minutes for EI 25 in HC-110 dilution B. I think I've used this time successfully, though I usually develop it in PC-TEA. Nothing is very much like Rodinal, which uses an uncommon developing agent and is famous for interesting edge effects, but IMHO, at the beginning it doesn't matter too much *what* developer you use as long as you find it convenient to work with---this stage is about getting up the learning curve, and the differences between developers are going to be down in the noise compared to the other variations introduced by figuring out your workflow.
