The east track does indeed have much more runoff. Funny that you mention that wall. As one of the CCS's southwests more courageous racers named Rick Bucher actually rubs that wall almost everytime he comes onto that straight. When interviewed on the subject, he states that " yeah I get a bit close but then again rubbing's racing" Then again that's the same wall that ended Fred Merkels career back in about 1995.
Its no worse than Pueblo however and just not a place to try and pass on the outside. It does get a bit slick when it's cold there just like pueblo. Take care
