I and others have kind of de-railed this post, "DUKE's Saw Chain". Thankfully other's have carried the side rail further off the tracks than myself.
Back to DUKE's saw chain.
I have used several of Duke's chain in three pack's of different DL counts, 3/8" plus a few .325" and a single 3-pack of 3/8" LP. Pleased with chain performance vs cost in all cases. Happy enough with the quality I have ended up with more than a half dozen of Duke's 3-pack's of chain. Based on my current experience I bought two 100' reels of chain. One full comp full chisel and a second full skip full chisel, both 3/8". Packaging of 100' reels definitely could be better, a bit disappointed here regarding spools coming apart in shipping. I have never had to spool out 60' or 70' foot of chain on the floor to unbind chain. Packaging of the reels sucks but the chain has so far proven to be good. Good value for price. Pleased with the product.
All experience is regarding the original "red label" chain. No experience with the newer "blue label" version
