just a tick over 70 with the 25 mirage non plusses at 4900 rpm, 69-70 gps with 23 mirage non plusses at 5400 rpm+ 
. hope this helps. both of my sets of props are unlabbed, i know my 25's would pull a few more rpm's if they were labbed but i don't see the need

Thanks guys. I am thinking the 25's will do the trick. I am running almost 70 on the speedo (not GPS) with the 23's at a little over 5100 but they blow out as I try and trim them to get more. I am sure if I had a better pair of 23's it would work better. I will try the 25's this weekend if I get a chance.
