So, I'm looking to get better at HU LHE.

Right now I'm doing ok at the 50c 1$ tables at stars but that's not exactly a level where I can get better, but I'm kind of worried about going up in limits without an improved knowledge of limit HU, which is nowhere near as popular or talked about as something like plo or hold'em, thus a lot harder to find.

So if anyone could point me in the right direction or share their philosophy on the subject I'd be glad to have it.
