Prop suggestion
 

I have a 23' Nordic Venture running a 21p Miage Plus. W/ this prop I am turning 5300 rpm @ 65.6 mph (GPS). My setup is a Gen V 502 Mag (stock except for EMI exhaust) and 1.5 gears. Looking to squeeze a bit more mph w/out dropping rpm below 5000. My thoughts: 23p Mirage plus labbed, or 24p Bravo 1. What increases could I reasonably expect from this change? Don't know which prop would best suit this hull. Any input would be appreciated.
