A tight twisty passage that's close to an entrance is The Snake from County Pot to Oxford Pot. I think it was the only way in to upper Easegill until County was opened up, and had a bit of a reputation (which is all I'm suggesting it on, I haven't done it)
It's actually not very tight, but it is a little damp and has a nasty little climb down. There's an interesting start to Flashbang Crawl between Wretched Rabbit and Depot No 1 Passage.
