With the 144 big bore kit I think you'll be happy for at least another year. I'm a fan of two strokes though.
I love the 2-strokes as well, the sound and power band is addictive.

Here is a quick vid my buddy shot a while back of me and some of my other buddies at a local sand pit....this was my 4th time ever on my bike...so I'm by no means a superstar in this video, this was also before it blew up.
I'll try and get some woods riding videos up soon.
