I don't quite have 20 bottles I'm saving, but I do have my share that are waiting for a special occasion. I can say I do exactly what you speak of (save the good, rare bottles and drink more readily, less expensive ones) and I don't feel bad at all. I do believe your Golder Still is a limited release, so in a few years if you were to crack it out and pour some at a whisky club meeting or what have you, I imagine you'd be pretty popular for sharing a bottle no one else can find except maybe at an auction... All I'm saying is you shouldn't feel bad about saving them for something, sometime, even if you don't know for what and when.
On another note, I keep my collection out on display at home. My Scotch is my art work. I love looking at the bottles (and some of their containers, such as the one in my Avatar & also on my shelf, a 25yr Laphroaig CS 2009 Edition, or Arran's Robbie Burns' 250th Anniversary Edition). I save on decorating this way
And while I wait to open the 25yr, I sip on my 1/4 Cask
