I was lucky enough to get the third copy of the new WW 300 series constant speed Propeller.
It's a 72' three blade with a much more compact hub. All up weight is 37 lbs, so around 7 lbs less than the 200RV. I have a happy 9 yrs and 1000 hrs on my 200RV.
Initial findings:
Climb is dramatically better, my meter always pegs but light on gas and single seat it takes around a minute to go from my field at 300 feet to 3300 feet setting the speed at around 100 knots. It is quieter, more of a difference than I was expecting.
I have a lot of hours on the 200RV for comparison and after I get above 3000 AGL my typical cruise climb set up for a trip is to have the autopilot maintain 500 ft/min and generally I get 150 knots *true* up to 11,500 ft. With the 300 series I'm getting around 156.
Cruise appears to be almost the same, maybe a few knots faster but I haven't done any trips yet to get a solid idea. I do an econo cruise at 160 knots and 6.5 GPH around 11k usually.
Spinner installation is also easier too.
I'm running it on a XP-360 with dual lightspeed IIs
Pictures at the end.
