Truthfully, how many of us know what 'sluggish' or 'edgy' or 'rocker' meant when we first got in a boat? Your first boat don't need be a boat that does everything or anything well because your skills won't be there to maximize the boat. You need a forgiving boat, one with a little more volume and soft edges- that way when you get hit with that first side curler you don't freak out. Go Stomper or Karma then trade up after a few months. I'd stay away from a Burn - the outfitting is intimidating and frustrating. LL and Jackson make some easy to outfit kayaks.
