From everything I read this is by far the best.

Blacktail Mountain: 76 days. My own development, created while I lived in northern Idaho, a location which has cool 35 to 45 degree nights and short seasons. The fruit is dark green with very faint stripes, flesh is an orange red similar to Sugar Baby. Continuously, it is my earliest type in over 100 varieties grown each season. Fruit averages 6 to 10 pounds. Pkt $1.75; 1 oz. $7.00 OG

developed by the owner of Sandhill Preservation. This is the best seed company in my opinion. We should all support their preservation efforts.
