Here's what I can tell you in my limited exposure to the pennies and forward splits. They are a daytraders dream because they will run like crazy sometime prior to the split but will get absolutely killed after the split. The longs get there shares which is what they wanted but they don't gain anything off the pps...if I was long I would sell off and just start a new long position after the split.
With that said...I've never seen a stock that has so much going for it post split like lfbg...this walmart thing could be huge but I'll give it some time to run it's test and maybe buy again when we start getting closer to Christmas. Just my strategy...choose what works for you and go with it!
