I hated PNL, i really thought the SPR straegy was poor. The idea of raising enough pre so that you can happliy commit post just seems stupid to me. I did try it on a couple of tables and still remember getting stacked for 100Euros when AK ran in to AA and when AQ ran in to TT with QT3 flop. I dont think i will ever play like that again. (god these hands were over 12mths ago and I still remember)

I guess if you were a shortstacker it might be better, the maths certainly would be better. Its just not for me.
