And my two cents... Springbank and Highland Park are absolute musts. Likewise, there are many slightly peated to more heavily peated whiskies that aren't as big in medicinal/iodine notes but are on the smoky side, some less so, but I'd think they would be quite appealing due to their complexities and, hence, keep you engaged. A couple that come to mind are the Benromach 10, Benriach Curiositas Peat, Talisker Distiller's Edition bottlings, Glenturret, Edradour's Ballechin bottlings and Glenmorangie's La Santa bottling. Of these, I'm particularly fond of Benromach and Glenturret.
Another beefy whisky, but not peated, is Mortlach; it's surely a strangely produced bu complex Speyside dram. Along these lines, Glenfarclas and Longmorn always hold my attention. Single cask Longmorns from a couple independent bottlers are currently, and albeit quickly, disappearing from my current selections.
Of course, one thing you might consider is having more than one whisky open at a time. It allows you to pick from a range of whatever you happen to be in the mood for - something that may keep you more engaged and not tiring of one thing or another.
