I had a guy on here include a 6-pack of blue Eskimos in a deal we made - it was a welcomed surprise!!!! I also bought some 4-blade blue Delta's recently so I hope to have some stories soon. So far...the blue Eskimos have accounted for 2 squirrels.
The coolest "experience" I have is that one of those blue Eskimos is roughly 10' up in a tree on the farm I hunt back home in WV. It was the 2nd of two afore mentioned squirrels and ricocheted after the pass through. Upon impact, it broke the ferrule of the insert ...so the arrow was left at the base of tree and the head remains. It will be a funny reminder every time I frequent that bench.
Strangely enough, that's the not the only head I have in a tree on that farm. All others are reminders of glorious misses.
