Prop Question - Possible SS Upgrade

I've been playing around with props and went from an ali 3 balde 17 pitch to an ali 17 pitch 4 blade and get the stern lift I was after but lost a couple of knots off the top end. I decided to fit an ali 19 pitch 3 blade prop and tried her out on the weekend and am getting some stern lift and faster top end speeds by a knot or two at 300rpm less (6300 down to 6000) and using a lot less fuel (0.66L/mile vs 0.8L/mile) but I've lost a bit of accelaration off the mark and she's out of the hole a bit slower later than the previous props which I was expecting.

The $650 question is: if I upgrade to a SS 3 blade 19 pitch am I going to gain back some of that acceleration and holeshot due to less flex in the blades and possibly gain on the top end?

Usually in the past when I've bought a foil my arse has dropped... onto the couch to play Goldeneye 

Yeah mate got a foil and happy with how the 19 pitch performs but hoping to pinch back some of that acceleration and hole shot.

 Ive got a foil you can try, it was on a 150 Merc.

You can try it and if you are happy with it a carton of beer make it yours.

 Going to a bigger prop is like going to a higher gear. You're starting your car in second now instead of first. You can never get the same acceleration but you can get top speed and economy. Out of speed, economy and acceleration you need to decide which ones you want but you can only have 2.
