I dont know if there are more than 2 plans. Its either YC or go alone. Reason for sticking with YC is free access to paul graham :D and his suggestions. I think this is something priceless and if at all we are out of YC, I hope i have a face to face meet up with PG and convince/beg to be our mentor :) Just like George Bush quoted "You are either with us or against us", i would go ahead and quote, its either YC or alone :)
