If you like merino then why do you add synthetic fabric at the top?
You do whatever you like but for me all my layers are made of wool including the outer one. I use synthetic fabric when it is necessary which is when it is raining. The wool outershell being water resistant enough for snow (and wind resistant). No more smelly fabric for me.
