i believe joshinjosh bought a tank for pretty cheap(maybe free?!) and the middle brace was warped to where it was not taught (so it basically acted as if it werent there)..and the thing bows like crazy i have never see anything bow so much, we both think its going to burst... its kind of good if u want some excitement.. somepeople like to live on the edge and enjoy scary things..cutting that middle brace would sure be scary, i sure wouldnt beable to sleep well atnight=P
