It sounds like you are bored in your current role and the prospect of more exciting work is your main driver. I'd probably go for it, as long as I had enough savings to cover me if they had to let people go, and that I was reasonably confident I could find something else if I had to. For my whole working life, most of my jobs have lasted no more than 2 years, due to a combination of working for small companies & start ups, mergers, the dot com crash, redundancies and contracting. So finding a new job for me holds no particular fear. I do live in London though, so there's a lot of opportunity.
