Nic,
Given the variables you mentioned, I still would lean towards the SCB for even heavy oil, as the bomb core with the high load particles are a strong factor. While I have never thrown the SU, and I think that it is awesome, for me and my speed, I would have to go with it. Your game could match up with either one, and perhaps the core's density, of the SU, would make it a better choice for you. Hope some of what I have said helps.
