Advice needed: a GOOD Social Bookmark blaster (using Pligg lists)??

Hi guys,

I just wanted to hear your opinions, I was trying several tools to blast bookmarks, like:
Bookmarking Demon
GSA Search Engine Ranker (wonderful tool)
Sick Submitter
SB Blaster (Clyde's soft)

I am currently using the last one in the list, SB Blaster, and I am getting good results, very easy to use with auto-email creation, but the problem is that every Pligg list i find results in a very high fail rate, ending in a list of 10000+ websites with only 300 or so valid to use. It works but I am sure there should be better programs out there to use.
Could you please advice what tool can I try? I just want to do social bookmark blasts for Tier 2 backlinks, nothing more. Is there another friendly tool to use?
Thanks in advance!

I doubt there are 10,000 active pligg sites out there that have registration enabled and allow new bookmarks. Getting 300 out of a 10k public list probably isn't that bad.

I have like 2.7k that work with UD, i recommend ud for social bookmarking.

i have been trying sb bomber and i am getting horrible success rates for submissions. I am getting really good account creation success but no luck with submissions i keep getting invalid login , bad response bad request, errors. I am looking for other good bookmarking software but do not know what to use.

Anybody have any suggestions?
