Clear that 1000 hr mark in anything without bending it and a lot more doors will open.
If a twin gig happens to fall in your lap...great, but don't sweat on it...keep chalking up the incident free hours and it'll happen.
There's no big rush...1000 hrs is FA in the grand scheme of things, and the future for drivers doesn't look too bad at all. There'll be a seat for you somewhere if you stick with it.
Good luck.
