I had a chain a few years ago that I think was a tri-link & came with a tri-link 36" bar. About 2/3 of the way through the chain I noticed a cracked tie strap & replaced it... next time I used it, same strap cracked. Figured I'd over spun it so spun another one in... next use same crack. Figured the links might be wrong so tried a different brand (after comparing with the micrometer & filing bottom of the tie strap to match worn chain). Next use, same crack, same place. At this point chain was 3/4 worn so I didn't bother fixing it again... might still have it in the pile of stumping chains
