If you are thinking of going for peated Speysiders then there are a couple of crackers you should try...not sure what budget you are on though.
The Balvenie do a 17yr peated cask which is nice (around £75)
Benriach do a 17yr peated malt too (around £50) - this is quite lightly peated and smokey and not at all overpowering and very well . Its called "Septendecim" and got great reviews from Jim Murray (93.5 points!).
Benriach do quite a few different peated malts of different age, which you may think of trying.
