I run a compact crank with an 8 speed 12-25 rear cassette. I get less chain rub when I'm using my 34/12 combo, than when I use my 50/25. I never use the 34/12 combo for actual riding, but occasionally I will cycle through all the gear combos just to check everything out. Cross chaining with a 6,7,8 speed chain isn't as big a deal as it is with the thinner links in a 9, 10 or 11 chain. You shouldn't make a habit of it, but I occasionally will be in 50/25 for the last few feet of a moderate hill.
