RE: BME vs DA
For the 105, the Mejzlik 28-10 is a good prop and will turn in the 6200 rpm range once broken in usually. Switching to Xtreme110 jugs will get you 500-600 rpm over that right out of the box and you can expect to gain another 150 or so rpm upon break-in. I've been veryhappy with the Biela 27-10 as well for the 102/105 sized engines, but the 110 requires a 28-10. Same for the Menz.
I've seen really no difference in performance between props in the 3D environment, though the lighter Menz or BME props will spool up faster and are generally favored over the heavier Carbon props.
