Re: [ManagingPrime] To buy or not
Yeah, what everyone else said.....And if you end up making a stupid newbie mistake like crossing your toggles while packing (someone actually did that and threw it on boobtube

) the Potato is a slightly more forgiving location to deal with it than Moab.
I dont know of a FJC (at least in the USA) that does not offer gear rentals during the course. Great route to take for trying different sizes, types (vented/non-vented), etc. Most will give you a discount on gear once you've complete the course if you purchase from them.
Good luck and good on you for taking advise to stay the fuck away from Moab until you've got more exp.
