In reply to SenzuBean:
A few that spring to mind at Stanage Popular :
Eliminator - good jug hauling, bomber gear for every move, fairly strenuous so not quite what you asked for, but good clean fun.
Rugosity Crack - a really nice line, well protected with smaller stuff, and there are a couple of good finger jams on there.
Paucity - quite short but enjoyable, the crux isn't as well protected as the previous two but more balancey and very much worth getting on.
Whillans' Pendulum and Black Magic - steep and juggy then nicely delicate slab climbing up the rib to the left of Hargreaves'.
Congo Corner - quite a tough start up a crack, then more delicate traversing and face climbing.
Leaning Buttress Direct - only 5b for the first couple of moves, but good fun nonetheless, and classic break-to-break Stanage slab climbing.
Tower Crack at the Plantation is also good fun if burly jamming is one of your interests, and a couple of others that spring to mind are Portfolio at Windgather (steep and crimpy) and Ricochet Wall at Shooter's Nab, near Huddersfield (more esoteric and supposedly - but not - E1, with excellent, well protected wall climbing, then a wonderful splitter crack).
I've been doing a fair few routes at the grade recently (hence my reply - almost all of these I've done this year), and have found it really good preparation for getting more solid at E1/2.
Edit: Good job you're looking for grit routes! All of those save Leaning Buttress Direct are superbly well protected, I'd say, with zero chance of hitting the ground assuming you have a competent belayer and can place gear properly. LBD only has 5b moves to leave the ground, in fairness, so you can just get your belayer to spot you, but admittedly after that it's more like a couple of 4c/5a moves and then progressively easier ground to the top.
