I have a very similar situation. The initial prediction by FTDNA for my 12 marker haplotype was R1b. Since then they have changed the haplogroup to no prediction. (My ysearch id is 6M79M.)

When I put my values into Whit's predictor I was underwhelmed with the strength of the prediction of R1b and Q wasn't far off in the percentages. Frankly, I was skeptical of either haplogroup being mine, since my paternal line is from Sicily, and I had no exact matches or one step mutations in FTDNA's database which is full of R1b. The closest matches I had were 7 two step mutations.

Here are the percentages in Whit's predictor for my haplotype when I tried first 12 markers, then my 25 marker values and then my full 37 marker values:

1st round (12 markers): Q - 57/R1b - 50; 2nd round: R1b - 31/Q - 30
1st round (25 markers): Q - 68/R1b - 43; 2nd round: Q - 46/R1b - 20
1st round (37 markers): R1b - 47/Q - 39; 2nd round: R1b - 27/Q - 20

Someone earlier in this thread suggested that the Pierce surname project participant who has the similar situation to mine upgrade from 25 to 37 markers. As you can see from my example above, that upgrade may provide no more certainty to that person than my full 37 marker haplotype did.

I think that person should do what I just did - order the multiplex product from Ethnoancestry. My sample is at their lab and I am waiting for the test results, which should be available before Christmas. It may be that I will turn out to be R1b, but with what seems to be an unusual haplotype, I want to be sure with a SNP test. I will report the results of that test to the list.

Could you give us a breakdown of his haplogroup prediction from FTDNA (how
many perfect matches with which haplogroups, how many one-step mismatches, how
many two-step, three-step, and four-step)?
