Disclaimer: By no means am I an expert, but went through quite a few bottles last winter (and currently stocking up for this winter).
I, like you, love the Laga 16, I think I've gone through three bottles of it since I started on single malts and will always have a spot in my cabinet. Try the Bowmore 15 Darkest. It's got all of the characteristics of an Islay, but something about being finished in a sherry cask gives it a different dimension. Though it definitely isn't as smokey/peaty as the Laga, I still enjoyed it.
This is a great thread btw!
