When I think nutty, it's not RY4 that I'm looking for, it's a quality 555

RY4 is generally a tobacco base, caramel and sometimes vanilla. Some RY4's (the ones I dislike) are way too heavy on the caramel/sweetness. What I've always liked about DK's is that it:
1) it had their tobacco base, and it comes through very nicely
2) was not heavy on the caramel/sweetness
3) had a slight touch of smokiness to it
Mainly it was #1 and #2 though

Anything that smells like cotton candy on exhale would definately be too much on the sweet side (for me).
