Anybody know for sure if Atlas mates to H55? Adapters available? I called AA and they didn't explicitly know, but are currently researching. I want to throw D70 in the rear (D60 up front). The split case is pass. offset. I could probably cut or re-tube the D70 to match the offset, but am skeptical as to the strength of the split case/D60/D70 combo. An Atlas case would be awesome. FYI: Don't want to get rid of the H55. Any other cases known to replace the split case? ???
