limit or pot limit?

Dispite suffering from manflu i played a little 50/1 PLO8 today to see if i can earn enough Vpps without increasing my hours to keep supernova for a few months. I tried 25/50c but the tables were so tight that only about 1/3rd of pots saw a flop to pay any rake and then only when it was monster vrs monster was there any pots worth any note.
Moved upto 50/1 and suddenly everyone loosened up, this was better pots were worth winning and playing 3 tables (all that was open) i racked up the 100vpps and hour i would need if i wanted to keep supernova.
Having played mainly limit cash for the past 8 months the switch back to PLO8 seems strange, took on and lost a few too many flips i think. first 6 in pots over 100$ i lost but was only 200$ by the time i got it in with oppo drawing to runner runner for a 198$ pot and got back to 100$ down.
The snow is going to help me this month as i have no plans to go anywhere till the thaw even the pub is getting the cold shoulder. So over the next 2 weeks i need to put in around 5 hours a day to achieve my goal.
With the stella rewards and the reload bonus it also gives small targets on the way, already claimed first stella bonus and just an hour away from getting the first of the 3 reload bonuses (split them into 3 $200 deposits seemed more senisible incase i need to go on bedrest or get called into hospital any time soon).
