My first choice would be the Caribou, because of the deflexed riser and accuwheels. I like the riser and grip on the Caribou much better than what I've got with my ProTec. Second would be either the Scepter or Cougar. It would come down to a coin flip between them.

I don't know anything at all about the Darton. You just don't see Dartons around this part of the country. No dealers anywhere in the area.
