People in any R1b subclade from R-M269 on down should consider going to 111 Y STRs. R1b-M269 (actually R1b-P311's) expansion across Europe is now being documented by scientists as a fairly recent timeframe - the Bronze Age. This means that R1b people from Europe typically have STRs that follow along with the Super Western Atlantic Modal Haplotype and our tree looks more like a bush. We need more STRs to discern our haplotypes in matching systems and analysis. Please look at this excellent presentation by Dr. Maurice Gleeson at the November FTDNA conference. https://www.youtube.com/watch?v=rvyHY4R6DwE&feature=youtu.be He does a nice job of going through the ins and outs of SNPs and STRs in a real case surname-cluster study for R1b. He clearly points out that 111 STRs are needed and even that is not without vagaries. He's also quite entertaining! This video is well worth the watch and backing up and looking at some of the charts twice.
