Marco,
I'm the same way.
I usually fish streams that don't require sinking lines.
In addition, I try to fish dry flies most of the time. I will, if absolutely nothing is working on the surface, occasionally switch to a nymph, but usually head for lunch or a beer or a nap until I can get activity back on the surface.
I am convinced that the vast majority of the trout's diet is sub-surface, but I so enjoy seeing them rise to my offering.
