I'm fine with using square and rectangle tube on the outside as bumpers and such. Yodaman's pics of the square tube exo look good but i'm looking more for an interior cage. The IH8MUD forums generally lead to round being more popular, the square and rectangle applications seem to be case specific and have worked so far but this kinda leads into the realm of "normalization of error" meaning it works and hasn't had problems yet but there is potential for failure more so than round DOM. I'm thinking I may have to sacrifice some space and just go round. Thanks for the opinions and info. Keep this thread going if you wish.
Thanks
