I can see that you are: M124+, L295+, L722+, L294-, L724-, L723-
Yes, The best SNP for you to go for is Y1280.
Unfortunately, I have sent several emails asking FTDNA to add SNPs to their list but no response from them at all.
The best/super fast way and also cost effective is to order any SNP you want from yseq.net
I don't see the Y1280 SNP added in their list. But you may "Wish a SNP" for only $1 and they will add it usually in less than 2 days.
You may tell them the SNP name and that it is found on YFull.com Tree: http://www.yfull.com/tree/R-M479/
After they add it, you may order the SNP for only $17.50 + $5.00 (For shipping the tools).
Then if you want to order additional SNP later, you may use the coupon code IDONTNEEDAKIT to get a $5.00 discount.
If you decide to order from yseq, let me know so I note your kit# at yseq and add your new subgorup name on the R2-M124-WTY Project after the results come out.
