I thought I'd just posted a longish response to this, but it seems to have got lost in the ether.
The Tournado is the same as the BreakAway, which has had excellent reviews. I quite like them , though the Tournado I saw was in beige & brown - not my fave colours really.
If you wanna go the S&S route, don't feel you have to go with Thorn - there are much better builders who use them. Roberts, I think, and Bob Jackson.
