Upper/lower Splits

Does anyone have any good recommendations for a good upper/lower split?

I did Stronglifts last year, then did a short bulk cycle with an upper/lower split, then did a round of another Stronglifts-like program. But I've stalled out again with majority of my lifts and want to switch it up. Also, my schedule has changed and I'd like to be able to go to the gym back-to-back days when I can. Stronglifts didn't really allow me to do that once the lifts got harder. I could go back to the upper/lower I did in the winter but any other suggestions would be greatly appreciated.
