exploring DNA matches by total cM and cM in the longest strands #dna

In screening DNA matches for close relatives ( ~ second cousins),  I typically pursue matches with total DNA of at least 125 cM along with longest single strands of at least 30 cM.  I often come across identified matches of much less than 125 cM total, say 80 cM, but with longest strands of say 20 or 25 cM.  In other words, with an unusually high percent of matching DNA in the longest strand.  Can anyone enlighten me as to whether these matches (characterized by relatively low total cM but high cM in the longest strand as a percent of the total) are also worth pursuing?
