Definately the coiler. The dawg is a cross country bike that is not ment for people of yor wieght, or jumping, and especialy not people of your wirght jumping!

You like to go down hill fast and jump, you need a sturdy bike. The stinky might even be ok for you. Also, the geometry of the dawg is not going to feel as good as the coiler when jumping or bombing hills.

I love konas and have ridden most of them. I took my friends coiler for a few days and loved it. I was surprised at how well it could be peddaled (spelling?) and perform like a hard core freeride bike. If you have any specific questions, just ask.
