One thing to possibly check on or take into consideration: Most (likely all) backplates have the holes at 11" on center, so things should be basically completely interchangeable that way. The holes in most wings should match up with the plate holes.
But, there is no guarantee that cam strap slots will line up amongst all different wings and plates. Many may. I have two different brands of wings and they both fit on my plate; but I have heard this is not always the case. Just something to check on or measure.
Also, on some plates the cam band slots are lower than they become if/when you add an STA. This might not matter to you if you don't need or want the tank riding lower. And/or you might modify the STA to suit.
I don't mean to overly complicate things. I have a plate with slots, two wings that have built in "stoppers," and an STA.... and they all fit together (well on one wing I would have to remove the wobble stopper to use the STA; on the other one they just fold out of the way).
Just some things to check on. I enjoyed trying with and without STA, and experimenting with tank position and etc.
