Ignoring your terrible spelling of Penderyn (and presumably Madeira)
I polished off a bottle of that last night. It's nice, very drinkable. Very sweet for me, nice mouthfeel though, very full flavoured. It was a Christmas present, so make of that what you like when it was alongside 3-4 other bottles on the go
Edit: It's always nice when people buy whiskey presents that are slightly different. I gave up keeping a list of my most wanted and told people to go to a shop and get recommendations heh.
Edit2: I got bored going round and round with all the recommendations and looked a bit more into that Bunnah' 10yr G&M edition. Went with my gut and bought the last bottle of that from MoM, plus the Hazelburn 10 to scratch that Springbank itch (hopefully). Will report back.
The Clynelish, Oban, Arran are all on my to-try list
