In reply to chrismcd23:
Cross-town traffic at Cambusbarron was my first E1, it's very well protected at the hard bit, so made a good first E1 lead.
I'd also recommend Slots at Limekilns, more of a highball boulder problem really, but I reckon it's alright if you have a spotter. It's one of the few other E1s I've lead.
I also remember trying Wall Street at Clifton near Dumfries (so not really central belt) and it's very well protected so probably a good choice, although it is quite sustained.
