HHTT mining pool changes?

[GrapeApe]

I am very new to mining I found a pool I like  HHTT and love it. But recently there have been some changes And I would like someone  to explain them to me. PPLNS in particular vs the old PPS. My hash rate is below 2 M/hs right now but I am almost finished building a machine that should give me 450 M/hs and I am waiting for two BFL Labs Jalapeno rigs which should put me at a healthy 9000 M/hs when or if they ever come.But someone please tell me I'm not wasting my time trying to stay loyal to fireduck and his pool.BTC
