I'm not an expert on Vermont, but since no one else has chimed in...
I've fished the White River and it's tributaries a bit, and I know that in the summer there is some very large fish to be caught.... as long as you're fishing at first light.
If it was me, I'd concentrate on some of the mountain brooks in the national forest area. Especially the "young" beaver ponds, ones that haven't been around long enough to get silted in.
There's a lot in that area.... all you have to do is find them
The simpler the outfit, the more skill it takes to manage it, and the more pleasure one gets in his achievements.
