You can't go wrong up there. Bait selection will be very easy. Grab some Nipissing jigs or tie your own. Jig head with a trailer hook. Nightcrawlers will work just fine. They'll catch the eyes and the bass even an odd pike. Any traditional pike lure will catch them up there. They're everywhere. As for the muskies, don't get too wrapped up in them. They're certainly there but with two young boys, you'll spend ALOT of time looking for them with little action for the boys. You have to put your time in to get them in the boat.
I've been staying near the mouth of the French for about 30 years and I've also stayed in the West Arm at Lakair and Sunset. You can't go wrong wherever you pick. Good luck.
