But it's a brand new pair of skis, they should most definitely be matched. Especially since it's summer and you aren't exactly skiing them tomorrow.
Call Salomon and complain, 1/8 inch is actualy an unacceptable variation in my experience, especially from a company that large. They press those skis in automated machines all day and then match them up afterward. Either some quality control person didn't do their job, or just as likely Salomon sold some mismatched pairs to an online clearance dump and them sold them to you for half off whilst maintaining a killer margin and not telling you ahead of time they are mismatched.
Surely your skis will decamber with time, but they should do it at the same rate by starting the exact same.
