I just did a no-sparge, low-gravity IPA a few weeks ago (~1.030). Quick, easy, and satisfying!
Basically used "Pliny the Toddler" malt bill with my normal IPA (~1.065) hop schedule. I don't think I'm going back to the bigger IPA...
I LOVE how it showcased hops with a clean, dry beer. A touch of grainy, biscuity malt flavor from high quality MO/pils keeps things interesting. Bitterness is sharp but clean - I adjusted to ~ 250 ppm SO4 and used all FWH and late hops to bitter.
