Prop selection for Hurricane 630 with twin 75hp

My zodiac hurricane 630 with twin 4 stroke honda 75 hp (carbed) has a towing arch on the back. The props on the rib right now provide plenty of power when you are towing something like ten 22' sailboats, but when you are trying to get the boat up on a plane when you aren't towing it just doesn't have a lot of punch and I get a ton of cavitation during a hole shot or when I try and tow a water skiier. I have to basically have the engines full trimmed down to get the boat up on its plane. I am thinking of adding a set of smart tabs to get the RIB up on a plane faster, but my guess is the props I have aren't the right size or pitch. Any thoughts on what size or pitch I should use?
