I will subit to 25-35 Directories each day. 
And guys I would like to clarify that not all the directories are going to list your website its only 25-45% of the directories which will list your website.
As we are submitting to 25-35 Directories per day so it will look natural to Search Engine. I would like advice you guys to try it out. It helps for sure as you are getting free one way link. [Remember no Reciprcal links needed ]
Pls PM me for details.
Thanks
