I have been running a 50/30 on the same crank arms on my Roadeo, phil 103 bb.
I love it!! Only shifting onto the 30 for long or steep climbs. In the rear I have a 6 spd 13-28 freewheel and have not had to use the 30-28 yet, even on what I consider my "Test" hill that convinced me to put a tripple on my cross check. That being said it has a lot to do with the frame/drivetrain/tire/ rider interaction. I am convinced of this more and more every time I ride. I bought and restored an Eisentraut Model A from an uncle, and rode a hilly 40 mile loop with a 53/42 up front and a 13-28 in the back, roughy toughys on the rims. I flew through it and climb hills that I need a granny gear for on other bikes. That is what drove me towards a Roadeo. Back to your question, I run a 20 tooth spread, and use a flat plated shimano deerhead derailleur to avoid rubbing the crank arm, it works outstanding for my needs.
