If one is deeply interested in this hobby you don't want to miss what you could have easily known.<br />In all cases, if you don't upgrade beyond 37 STRs, you may miss a match just beyond the FTDNA match limits at 37 that falls in place at 67. Remember, you are almost doubling your marker set when going to 67 so a lot can happen in the 38-67 Tiger Mikehttps://www.blogger.com/profile/03309295785529466229noreply@blogger.comtag:blogger.com,1999:blog-5443730660032753146.post-57335059861369937752016-06-21T19:53:43.828+01:002016-06-21T19:53:43.828+01:00Maurice, please consider two additional reasons to...Maurice, please consider two additional reasons to upgrade to 67 and/or to 111. The first is to identify STR signature markers, which may help guide future testing and place you in the correct cluster. This can save you money on future SNP testing as well as help you identify who you should recruit for additional SNP testing and as potential people to work with in funding additional SNP testing.<Tiger Mikehttps://www.blogger.com/profile/03309295785529466229noreply@blogger.comtag:blogger.com,1999:blog-5443730660032753146.post-67235004609263731892016-06-21T12:21:52.421+01:002016-06-21T12:21:52.421+01:00Good point, Israel.
