I've ridden LBL and Turkey Bay. You will be fine on the main trail, and a great deal of the secondary trails, especially if its dry. If you venture off the main trail, as long as you have somebody with you to give you a tug if you have trouble, I say go for it! Make sure you have good tow points front and rear.
In the long run, though, you'll want 4x4. So unless its a great deal on the 2wd, you might be better off waiting for what you really want.
