n8tive97,

My biggest issue in the field, other than being out of shape, is being able to judge distance. That's why I lean a little more to the light side in bullet weight to favor a flatter trajectory. I'm not much for hunting the thick stuff but if you are then the 200gr may serve you better. Again, I have no experience with the .06, but look at some ballistic tables and think about the kind of hunting you want to do, that should help you decide, you can always change it up.
Truthfully a 165gr out of an .06 will put anything in this state down if you do your part. If you're using the .06 strictly for mulies, consider something like a 150gr, it should shoot damn flat. All my deer I've taken have been with 140 gr.

The lead issue may be overblown, but I'll play it safe, what the hell.
