YSEQ has a single SNP test that would confirm whether you belong to the R1b-L2-FGC13617/FGC13619 block.
Cost is $18

Or if you want a test that explores other branches of R1b-L2 as well then for $119 there is the R1b-L2 snp pack from FTDNA.
Includes the following SNPs on the haplotree: U152, L2, Z49, Z367, L196, PF7610, CTS10009, CTS3080, CTS5689, A6454, BY2823, DF110, FGC10516, FGC22501, FGC5301, FGC5344, FGC5345, FGC5356, L408, PF6658, S1567, DF103, FGC14641, L199, FGC22538, FGC22516, FGC22528, FGC22533, FGC22500, FGC22503, FGC22512, FGC22513, A1704, A1706, A1717, A1722, A6455, BY1020, BY1145, BY2381, BY2824, BY2825, BY2826, BY3477, BY3478, BY3479, BY3480, BY3481, BY3482, BY3483, BY3484, BY3485, BY3486, BY3487, BY3489, BY3490, BY3491, BY3492, BY3493, BY3497, BY3498, BY3501, BY3503, BY3504, BY3505, BY3506, BY3507, BY3508, BY3509, BY3510, BY3512, BY3513, BY3514, BY771, BY806, BY831, FGC10525, FGC10536, FGC10543, FGC13617, FGC29428, FGC29470, FGC32882, FGC36273, FGC4166, FGC4177, FGC4183, FGC4193, FGC4213, FGC4220, FGC5303, FGC5306, FGC5308, FGC8154, FGC8158, FGC8178, L409, PF7609, PH3790, PR5365, S1555, S1561, S1566, S1569, S1570, S1573, S18462, Y11667, Y11931, Y11932, Y11933, Y3960, Y3961, Y3964, Y6763, ZZ48_1, ZZ48_2
Includes the following SNPs that are NOT on the haplotree:
BY2895, FGC13620, BY3496, BY3499, BY3500, BY3502, BY3511, FGC13621, FGC13623, PF7599, PF7603, PF7604, PF7605, Y11232, Z7054
Personally I am interested whether you are FGC13617/FGC13619 and $18 for a single SNP test from Yseq seems to me a fair option.
