the minus two swingarm is great in the woods. esp. when you need to get the nose up. for example going over logs. the turning radius is much better which is also use full when in tight areas.
as for the hills the nose goes up real easy when hitting a steap incline. if i could doit again i would prolly go with a minus one but if your not doing any hills stick with the minus two.
hope this helps,
