Method: Short Line Nymphing/2 flies
Location: Let's say Monument

Let's say I have been fishing a particular stretch of water...say 30 yards long by however wide.
I have had a couple of hookups but nothing to rave about. My questions are:

1)Do you move onto another piece of water?
2)Do you fish the same stretch again?
3)Do you change flies to fish the same stretch?
4)Switch to long line or right angle indie rig?

Obviously no right answers...just curious to hear other's thought processes on this.
