Oh deer god no, DO grab the musket, but you should still get the Sneaky Decoy(and Whirlwind) nonetheless. I'd never suggest skipping the musket to you.
The musketless roathus lagoon is terrible and only saves time if you're already incredibly good at the game, but Sneaky Decoy can still be used to make Anne faster even if you do take the musket.
