Hello
A few points to give you some flexibility:
1. Line- I would go 30 lb; look around and see what is best suited for your reel, fire line etc are good starters but you want to get the thin line to get the extra distance in the casts, or as mentioned earlier get multiple reels (bait caster etc);
2. Leaders- everyone talks about wire leaders; what they don;t tell yoou is after a few of the bigger fish they will kink and start to tear. Spend the extra money and get "Titanium". You will find that one will last you the entire trip and remain straight as the day you put it on;
3. Lures- I would recommend the "Grandma" lures; these are exceptional for "multiple use" You can catch huge pike and walleye with the same lure. The 10" to 12" are good size. Don't be fooled by getting it too big, Walleye will hammer these lures. The only draw back is where to buy them:

I believe they are available in Calgary or online of course.
4. Keep your gear and fishing "simple stupid"; you will be surprised how far a few good crank baits and multiple casting will go.
Anyway good luck, don't forget to post your pics!
