I've been on dozens over the years so I have a bit of experience here. When you're going blind, first time ever, the best thing by far you can do is solicit advice from a resource like OFC, or (can I mention another board?LOL!), Walleye Central. After you've narrowed down your choices, ask your selected outfitter(s) for references you can call. If they're not willing to give you any I'd shy away from them.
Many will tell you to attend sports shows where a bunch of outfitters have booths and you can talk to them face to face. I disagree. The best outfitters don't attend those shows at all, they're business is all repeat and word of mouth. The guys at the shows are usually the ones who have to fight for every booking they get.
Fly in trips can range from 5 star expensive lodges where your pampered, to relatively inexpensive "outpost camp" trips where you take care of everything yourself including food. They're usually smaller, more intimate lakes with the outpost being the only camp on the lake.
If you're more self sufficient and appreciate the isolation, the outpost camp is the way to go. Definitely more my cup of tea...
Anyhow, you can do all the checking and asking as I mentioned above OR you can just ask me!
I'd be happy to offer my recommendations to anyone who's interested.
cheers, Mike
