I could be wrong, but i think the achievement on s1: terrance village might be missable. If memory servers, fireworks dont respawn. Or they didnt in original trilogy anyway.
I currently have a group of 5 set up for ALL raid achievements.
We are all level 40 and at time of post 340+ light. We are mainly aiming for alt Friday and Saturdays. But if more people join then sessions during the week.
Due to forum rules I can't post link. So hit me up on xbox live if your interested and I will send you the link.

^^ no one will boost if you haven't got the equipment. The achievements can be difficult for a group of fully maxed out amps/guns. So someone new to the game has no chance and is only going to make things harder
As a little tip. If you can manage to keep yourself in the air by up hill grappling and stay within course boundaries, you can make all the extra points you need before hitting the last checkpoint. Its a slow process but I helps on some of the tricker courses
