No first hand knowledge, just info in passing. Nothing really bad about them.
The sheep population in that part of the state is struggling. I would ask for success rates for the last 4-5 years. and check references from past clients of this year and last.
With the closure of 19, there are a few guides moving into their area, or so I hear. could be more pressure in the coming years.
I'm not sure if there are better or worse areas to hunt, to be honest. Sheep populations are pretty low statewide, Sure there is still success, but it's nothing like it was 10-15 years ago. The days of seeing multiple legal rams on a hunt are long gone.
Good luck
