I am U106+Z381+Z156*. It took me six years to get from U106* to Z156*!
I can look at the tree and see all the SNPs upstream and I dont understand why it has taken so long to find the SNPs downstream. I believe that Z156 is between 4000 and 3000 ybp. Why can they not find the SNPs downstream to the present? There are seven thousand U106 people tested so far.

By Z156*, I assume you mean Z156+, L1- and P89.2- ? If not, L1 and P89.2 are obvious testing choices.
Some individuals just had a significant genetic bottleneck very near the creation of their older Y-SNP, you may just belong to an origin that is not geographically well tested or your particular genetic community are not testing WTY (discovering new Y-SNPs). By looking at the number of Z vs. L Y-SNPs in your part of the haplotree, it appears that your genetic community is getting most of their new Y-SNP discoveries from the scientific community vs. the genetic testing community (proactive). Once the new WTY test comes online in the next couple of months, try to get volunteers in the Z156* community to share the cost of the WTY test (estimated to be $1,000). What is the geographic origins of Z156 ? There is a lot more WTY testing for Irish, Scottish and English Y-SNPs since those geographies dominate the ethnic background of the US genealogical community.
There seems to be plenty of Z156 candidates in the Isles. There is a Z156 modal at ysearch (FUZKX).
I still dont understand why there are no SNPs downstream of M222 when you have so many men tested from Ireland.Do you think FTDNA are holding out on ye? Even if M222 is only 2000 ybp there has to be an SNP between M222 and the present.

Most SNP's are either discovered via WTY or via projects like 1000 Genomes. In general there hasn't been many M222+ doing WTY. As a result it's hard to find downstream SNP's. Hopefully when they launch the new version (With massively increased coverage) it should lead to discovery of several SNP's that would breakup M222.
In contrast more and more SNP's are been discoverd up stream of M222. Back in 2003 M222 was down as been directly under M269. (M269 -> M222)
In comparison now the path from M269 to M222 is the following:
M269 -> L23 -> L150 -> L51 -> L11 -> P312-> L21 -> DF13 -> DF49 -> DF23 -> M222
In the above list DF13, DF49 and DF23 have all been discovered in the last 12months. Before then M222 was regarded as directly under L21.
Z156 in comparison looks like the following at the moment.
M269 -> L23 -> L150 -> L51 -> L11 -> U106 -> L257 -> Z156
with the following SNP branches under it:
Z156 -> L782
Z156 -> Z305 -> L1 -> L132.2
Z156 -> Z305 -> P89.2
Z156 -> Z305 -> L128
Z156 -> Z305 -> L127.2
Y Chromosome Haplogroup: R1b-L21/DF41+
Mitochondrial DNA Haplogroup: U4*
Autosomal DNA admixture (K12): 42.5% North European, 38% Atlantic-Mediterranean, 11.5% Gedrosia, 6.8% Caucasus, 0.9% South Asia, 0.2% Southeast Asian
L257 is under Z18 a brother of Z381 which is upstream of Z156. FTDNA are offering me tests on my homepage and they are not up to speed with their own SNPs.I dont belong to any of them.
