I have read the other topics on this stand, but want to make sure I am not doing something wrong here ... I just got this stand (but thinking of sending back) to replace my very old, but so far trustworthy two tier x stand .. (plan to have pc1x, xk1, and deep mind 6 on the spider) .. of the 3 the PC1x is the heaviest .. I set it up and just put the pc1x on the bottom tier (4 legs were on stable surface, etc) and just did not like the rocky "see-saw" feel when playing at the ends of the board, etc - any hints?? similar experiences ???
