I just spoke with Hetom, the owner of Sky Valet, and he guessed (with emphasis on "guess") you might be a 10G for the 341 last. He said that the 341 is much narrower and sleeker than the 325. Also, also the 341 doesn't come in E, only C and G (with G being the equivalent of a U.S. EE). Hope this helps.
