Thanks for all the advice boys, I think that after sleeping on it I'm gonna go for the new Because Simple. At 1090, 380, +35, 71.5 I reckon it hits a nice middle ground, its cheap enough to warrant me to buy some other bits and I don't really need to go mad on an awesome frame as I'm not challenging for the elite class!
I did consider an Ashton but I don't think I could keep the weight down enough, still might swing to a new zoo if they've arrived by the time I order but if not I'll be happy with the because.
