It appears that all European haplogroups have either 26 or 27 as their modal value for DYS716. The modal for R1a is 27. In fact, I have yet to see an R1a who doesn't have 27, although there are no doubt some out there, and the ones who find a non-modal value for DYS716 will have found a valuable marker for their cluster or family.
For those interested in clarifying the structure of haplogroups downstream from currently tested SNPs, the slow markers in FTDNA's Advanced Test set might be more useful than the tests from deCODEme or 23andMe. They are certainly far less expensive.
The Advanced Tests have been very useful for me and my cluster. Our cluster of R1b-S116+ has modal values for the FTDNA 67 that are fairly close to the S116+ modals, and our differences are all on medium to fast markers. The two slowest markers where we differ from the S116+ modals are both available only in the Advanced Test set. Also, the two slowest markers that differentiate my family from my cluster are only available in the Advanced Test set.
