UH, I also hunted G7 in the early 90's and it was DIY. I also am nearing enough points to draw again and would recommend the DIY. I have hunted the unit three additional times with family members and we all killed nice goats, the last being near book by my dad.
As far as sheep go, I killed a ram on the South Side of I-70 between Georgetown and Guanella Pass. If you drive that road, pull off and glass to the South. It's mixed timber but you can generally pick out some sheep. My Dad killed a nice full curl ram between Empire and Berthoud Pass. Again, a lot of timber but you can glass and pick them out in the rocky outcroppings. Just my experience, hope it helps.
