I own four BWS noise kites and have extensively demo's the Griffin TRX's (also a couple of Argo's). The current version of either kite does not deserve the flack it cops. In fact, the BWS kite quality has been great for at least three years (that I have owned them) (it is true that you need to replace the P lines and the centre de-power lines more regularly than I would like, approx $40 bucks worth). They are both priced very well and therefore people seem to need to bag them to justify the cost of other kites (just my opinion). I have also owned North (still do), Ozone and GK kites.
The Griffin kites I have seen (2012,2013 models) look great and there are allot flying at my beach and they are holding up well, and not all of them are "cared for".

The BWS kite is not a great jumping kite, but it is alright - it is built for the surf and does it well. The bar is the best, for the surf. Never jumped the TRX enough to comment (I was always on a surfboard strapless).
I will be switching to the TRX's because it does everything the BWS kite does, but (amongst other things) has better range and a nicer loop. The TRX impressed me, in the surf it is an awesome kite for strapless.
Hope this helps a bit.
