Kind of late to the party here but, for what its worth, dont be scared of trying the Blackbird series.
I ran a 2 seat Colorado sand car with a NA J32 honda with a set of 32 Blackbirds. First tried a set of #2 paddles and that was perfect on the flats but on the steep dunes it just couldnt pull - too much paddle. Then we tried a set of #1 paddles. That was perfect! Gave it just the right amount of wheel spin to keep the RPMs where you needed it for the steep dunes. The extra height was a great improvement from the 13.00's but still gave the forgiveness we were looking for from stepping up to the 33's.
I also got a set of 31 Blackbirds, cut them to #1 paddles and have them on my 2000 Alumicraft. 2.0 Subi with a 091. I brought a set of 14.50 Dune Sports to swap out on our last trip out and never put them on because these blackbirds kick major butt!! They slide great, I can still light them up (200hp) and again, the extra height makes 2nd gear longer and more useful with less shifting through the smaller stuff.
Blackbirds are not just for sxs, they are excellent sand rail tires too.
