For your brothers who like peat flavor. Definitely give the Ardbeg Uigeadail a try. It has a stunningly complex pear flavor that is warm and not harsh. Also another one that is often over looked is the Longmorn 15yr

The best MacAllans are the cask bottling, easiest being the 12 year old that has been talked about on this page, but you can also find it easily in independent bottling for good prices. This is when a specific barrel is purchased and then bottled by and individual or independent bottler. These can very wildly in flavor and change with the barrels storage location and year. Very cool way to try out different flavors. I went to a store in Japan back in 2008 that had a whole row of just MaAallan bottling, there were probably 500 different bottles.
