The hunter start isn't random at all, that camp is always there with Alternate Start, even if you choose another start.
One thing you should know with the enhanced Companions questline, you MUST have subtitles enabled since it adds lots of dialogue, which of course is silent. Also, if you decide to do the Thieves Guild with New Salessi, you must change the default settings in the mod, since the enhanced Companions won't allow a TG member to join (something Arkas learned the hard way when he tried to con his way in - I had actually forgot about when I tried that! Kodlak literally said "go back to your friends in Riften"

).
I've changed the settings so that Jelissa won't have to do THAT many extra radiant quests and don't have to level THAT much, since she also will be doing lots of other things, I don't have THAT much time to play, and I dont want to wait forever before I'll be able to have Vilkas as her follower, and, if things should turn out that way, possible love interest and husband.
(My latest idea is to bring both wolf brothers to Season Undending - they would make a fine-looking bodyguard for the Dragonborn, don't you think?

And they all obviously will escort Ulfric there, too. I could even throw in Erik and Ralof in the mix, that would be... interesting...
