Use one myself. There are a few things I don't like about. It is a bit crap at dumping air IMO and takes some getting use to but thats not a big problem for me as I fly my suit not the wing. I am also not a big fan of its harness which is fine but it doesn't suit my build(skinny git with beer belly) I found I couldn't adjust the d-rings how I wanted because the clips etc got in the way so I made my own one piece harness instead.
It has a great back plate. The c/d plate is best I have seen IMO. It gives you lots of options for clipping things to it and lots of options for fitting tanks. Idea for holiday use when you want to twin up but have no s/s bands. I use a single large camband for twinning up on holiday with it and it works a treat. There is some talk about the bungee cord not lasting but I have had mine for about 2 years and I dive nearly every other week with it and mine show no sign of wear. The wing itself is well made and ios very tough and would IMO take some serious hammering before falling to pieces.
If you use a dry suit then stick to single bladder, if wetsuit then look a double bladder as this gives you a backup.
Have you seen the c/d
TCW? Havent used one myself but it looks to be much than the tdb
