Joe, my favorite prop for the Integral is the Falcon 20.5x14.5. Gives good vertical pull yet has some speed left for those windy days. However, the Advance could use anything from a 20x13 to a 21x14 without issue. It is powerful, runs cool and is very quiet. So, prop choice is very broad for the Advance. I think it is really more a choice of what prop to use with the Integral rather than what the Advance can handle. My Integral seemed 'happier' with a little speed so I stayed in the higher pitch ranges. My Integral was in the 10lb 20oz range depending on battery, if your Integral is lighter, it might be fine at lower speeds. You could start with a 20.5 x 14 APC, see how it feels and then go from there depending on whether you want more speed, more pull, etc.
