I picked up Rock Orso today because I had the gold sticker sheet for it (so pretty) and I really wanted B to try it out for stamina. The idea behind this combo is mode change for different heights, via shooting technique. For high track stamina combos use an aggressive sliding shoot to send B into "attack" mode and use Burn's recoil to KO other stamina combos. For low and mid-height stamina combos this technique wouldn't work, so instead you will utilize Burn's great stamina with the added bonus of 230. Use a very straight shot for these heights.

230B always shot first
Burn Cancer 230B vs Burn Cancer 145WD
230B Wins 12/20
230B: 8 KOs, 4 OS
145WD: 2 KOs, 6 OS
Burn Cancer 230B vs Burn Cancer 100WD
230B Wins 19/20
230B: 1 KO, 18 OS
100WD: 1 OS
I didn't bother doing a ful set of tests for 90 and 85 because of 100's results. I did some informal testing and 230B always won.
I did some informal testing against 135WD, 125WD and D125, and it seems that using the sliding shoot does not work against tracks lower than 135.
