L128 has been found downstream of U106 & P312 it has also been found upstream in L51 this makes it un reliable as a terminal Snp and should be re designated or removed from the ISOGG tree

Ballard, before saying this, we should verify where L128 has been found:
1) if all R-L51 are positive, it could belong to R-L51 and downstream
2) if only some subclades of R-L51 get it, it could belong to a common R-L51* ancestor of some of its subclades and to all the downstream ones
3) only if it is found in some subclades upstream and downstream an haplogroup, it should be declared unreliable.

From these data published by smal, we see that at least one of the Tuscans of 1KGP is possibly positive for L128:

NA20785 TSI L1099+ L128? PF2624+ PF2750+ PF3498?
HG01066 PUR L1099+ L128? PF2624+ PF2750+ PF3498?
NA20537 TSI L1099+ L128+/- PF2624? PF2750? PF3498?

From the about 2000 samples released by BritainsDNA we may understand that L128 is recurrent but not unreliable. It isn't a stable SNP from R-L51 to the subclades, but within a subclade it may be understood like a valid sign, thus the R-L11 subclades with L128+ are probably linked and this SNPs should be considered like a singleton within that subclade.
I said many times in the past that R-L11 is a paragroup and the subclades you are collecting are brother clades of U106* and P312*, no one of them is R-L11* as there isn't any U106* and P312*.
