Well going by the options that you presented a climber is way more versatile than a ladder and will get you into a heck of alot more places. Then your scope is pretty much the most important piece to the puzzle because you need to see what you're shooting at and does it fog all the time or in certain weather conditions? I would go for a new scope because whether you are on the ground or in a tree you need to know that your optics can be counted on during that moment of truth.
