I use em, but I try not to think too much when I do ?

Manfred, you definitely gotta get into Jazz then. The beauty about Jazz, it 'forces' you to think in scale/modes/arpeggio's for EVERY chord that comes along. And also, it allows you to break a few melodic rules, namely, you can play your Phrigian scale over any minor chord that comes along to give it that zestful sound..
I think it depends from player to player. More modern thinking is along modal lines but traditionally it was chord tones and arpeggios.

Something i picked up from a Jody Fisher book on jazz harmony is to keep it simple and focus on the melodic aspect of playing through the changes, and then adding other notes to add tension to the melody.
That is the whole truth and nothing but !
A lot of jazz players don't think one mode per chord because thinking about three modes for a single ii-V-I is too much mental arithmetic and doesn't necessarily help spell out the changes. Someone like Joe Pass plays modally but to him a ii-V-I is just one chord with a little "movement".
You can analyse Pat Martino's playing and see all kinds of modal funkiness, but he doesn't think in terms of modes, he converts everything to a minor and plays minor line forms which are pretty much modal soup.
Since minor pentatonics work well on the guitar and Dorian is only a minor pentatonic with two more notes, one method to play "modally" but keep the thinking simple is by converting everything to a minor and then play with one shape/mode : Dorian.
Major chord ? Play Dorian from the 2nd
Minor chord ? Play Dorian from the root
Dominant chord ? Play Dorian from the 5th
Minor 7 flat 5 ? Dorian from the 3rd
Phrygian sound over a minor chord ? Play Dorian from the 7th
Lydian sound over a major ? play Dorian from the 6th
The advantage with this approach is you can learn 5 Dorian shapes (which are just one or two notes more than the minor pentatonics you may already know) that fit well under the fingers and cover the whole fretboard and play over almost any chord
The hard part as Adrian says is being able to start from any string or note in the scale.
