Ah, I missed the part about him wanting to throw cut rollers. I still stand by my answer, I use my same roller discs for cut rollers. The only thing I change is the angle I lay it down on. Slightly US disc layed down at a minor angle will go SO far right to left (or left to right for LHBH like the OP). They will stand up like a normal roller, but will change orientation so they're standing up and rolling basically at 90 degrees from your lie. Its a tough shot to be controlled with, but you can get some crazy distance where the disc basically makes a hard right angle then rolls for 300 plus feet in a straight line. For me, I don't see the point of throwing backhand cut rollers with OS discs, because you aren't going to get enough lateral movement to justify that shot. Why bother with the roller their when you can just skip something?
They're two different shots, really. You can't get that US disc to act quite as straight in the beginning and still get them to cut the whole way. I also sometimes want to avoid the disc turning over in the air. But I see why you would stick with one disc to roll with (confidence/consistency).
I can get significantly more L-R movement with an OS disc on a cut roller than a skip, but typically I'll throw the roller over the skip based on ceiling issues.
Like has been said: with practice, you'll start to see rollers just like you see air shots now. "I want it to be in the air like this, land like this, roll like this for a while, and finish like this".
I like to stay max weight for rollers. A little more momentum to get through adverse features.
A Mamba will act a lot like your Vulcan.
