RE: Prop mods
For mono mods I'd remove some leading edge and taper out. One thing to keep in mind when trying the ABC's they have a 10 degree rake so you will need to loosen the boat up to get a fair compaison, dial in the boat to the prop.
Jim has some new props out for monos and more comming soon, I can't seem to keep the new ones in stock.
I like the ABCs!
