The first number is the leading edge/top of the blade's....pitch. the second number is the trailing edge's/bottom of the blade's pitch. A 15/19 grabs more water than a 14/19.
A 15/19 grabs the same amount of water as a 15/20. The 15/20 however moves the water along faster...so you'd have a greater top speed.
Over all, the steeper the prop the more ponies it'll require to spin at the maximun rpm/power band for your set-up.
If you're gonna drag and ride for fun...you should consider gettting an adjustable nozzle....larger rings for holeshot...tighter rings for higher top speed.
I don't believe with your set-up you could twist a 15/22.
You haven't mentioned a 3blade...skat makes the 3 bladed props...best for holeshot...closed course....type impellers.
