Choke is worth considering versus Stoneforge? If you keep them off hitting with a SoFaF, then Choke locks down nearly all of their lands.

in my own experience, RIP is really good vs RUG / BUG variants. It's not good vs Stoneforge sure, and it's antisynergistic with our KoTRs.

I think it is a mostly better Tormod's Crypt, though.
