Too much ranting and too less information for my taste.
Actually, NO information. Are you trying to tell us the stand and the soprano will tip over without the weight of a tenor on it? (I find that a bit hard to believe, but it could be) Or are you trying to tell us that when you pick up the tenor it has a tendency to pick up the stand with it?
Personally I rarely use pegs on sax stands; I prefer my "pegs" stand which has a heavy steel base and threaded holes for multiple pegs, so I can put flute, soprano, piccolo, or combinations thereof on that one stand. I never use multiple sax stands (like alto-tenor combo). I prefer multiple stands so I can arrange them according to the (often skimpy or oddly shaped) space available. I have also had near misses with picking up a sax and the stand coming with it - if a tall instrument on a peg was attached the whole thing could get out of balance fast - and you're usually in a hurry.
(Just for information, I have an el cheapo tripod alto stand, an elcheapo tripod for tenor, a Hercules tenor (which sometimes I use for alto), a tripod for bari (cut down and modified from a Belmonte type, to fit my low Bb accurately which no stand currently available can do without mods), a Hercules for bassax (extended and modded from a Hercules bari), and the aforementioned "pegs" stand. I've also tapped out the peg threads on all the stands that do accept pegs, so the standard 3/8 NC thread pegs will fit.) All of the above work well for me, if they didn't they would get modified till they did.
