I have dove both using and not using STA, rolling is nothing I've ever noticed. The tank will sit marginally more securely (read zero movement) if just using cam bands through plate and wing slots. I prefer using a STA, it makes dissembling my rig easier for cleaning, adds a 1lb+ of weight that I don't need to carry on a belt and is easier to put on/swap tanks on a rolling boat. It also allows trim weight pockets, using angled STA such as DR or AGIR, to sit a little nicer. I like the U shaped Hollis and a Halcyon STA as a 6lb weight can be added if required diving a drysuit or AL tanks. The tank roll control tabs found on the Hollis (removable) and Oxycheq (fixed) wings work fine.
(Based on my experience with Hollis wings, plates and STA, Oxycheq wings, DR plates and STA, AGIR plates and STA, Scubapro plates and Halcyon weighted STA)
