Replying to COC - which session?

i know its kinda late, but i just found out that theres a good chance i can go to one of the sessions. the problem is i have to find 6 days to work after exams before i can go. so i doubt id be able to make it to session b which i would like to go to. my question is, is session d really that bad? will the jumps still be big like 50ft+? and will the rails still be good and not like half of them taken down due to lack of snow? cause if sesh d isnt that great, id rather just save my money for next year and go then.
