Going with one rod you'll be making a sacrifice. Your options are
1.) Take two rods
2.) Take a shorter drift rod, knowing you'll be dragging line in water when you fish floats/jigs.
3.) Take the longer rod and suffer the difficulties of tight spaces, overhanging limbs, etc.
4.) Shoot the gap and something mediocre for both.

Bottom line: Get the right rod for the job. Don't sacrifice. Break one of the rods down if need be and put it in sling across your back for hiking in.
