why do you guys use SRB miner instead of CAST?
SRB does not offer any performance advantage, it is more complicate to set up and actually performance is very erratical, since any time you restart it, you may get a different hash rate, at least for me.

I have been using it for a couple of days on 2 rigs one with Vegas and the other with RX580 and I could not find any plus VS Cast.
Just wondering if I am missing something.
