I do think Tobin's STA-less system is a very good one. His singles rig package is well-priced, and you can get a lot of advice before your purchase that will ensure that you get what will work for you and the kind of diving you are doing. If you live in Nevada, you could be diving the California coast in a dry suit and need lots of weight and prefer a SS backplate (possibly with Tobin's weight plates in addition, which are a VERY elegant way to carry some additional weight easily), or you could do nothing but warm water resort diving, in which case you would want something lighter like aluminum or Tobin's Kydex plate. One thing I'm sure of is that if you talk to Tobin, you'll get good advice.
