Since the conditions are unknown, you should get rather flexible gun which is suitable to use both with double and single rubber bands. This will eliminate the mr carbon, they are not suitable to use with double bands.

My other choice would be the seatec gabbiano snake at 110cm length with double bands. Its good to use both with double 16mm bands or single 17.5-20mm bands. Very well balanced gun with sensitive trigger, bears all the advantages of the woodies ( heavy enough too ) but will need less maintenance compared to teak gun.
