Here's a big vote for the Slim Beauty!!!
Its really no harder to tie than a Uni or Albright if you are using heavy mono and start with a double overhand knot in the mono and tighten it until it "figure 8s":

I have seen a few ways to tie it - the link above is the best and easiest and shows the double-up braid that I think makes a big difference.
