I've landed countless very large pike with a 6 weight rod. Regardless of the context - the old adage still applies - it's not the size/weight of your rod, it's how you use it.
The down side to the lighter rod is that you can tend to overly wear out a fish since you don't have enough backbone to land him quickly. A buddy of mine used to use a 3 wt rod for trout fishing large rainbows and browns on a particular river. After a day of that I berated him after watching him struggle for waaaay to long to land fish. I'm thinking a few of them died due to the long fight.
That being said, if you are in a maneuverable boat it's not so bad as you can shorten the fight and still enjoy using the lighter tackle.
Bitch lake used to have some nice pike in it many moons ago - I don't know how it is now though..
**I'd go with much heavier mono for your leader, especially with a light rig. I used to use 40lb test maxima for my main leader with an 18" nylon coated steel leader for the teeth. Since you lack a heavier rod weight, 8 lbs is going likely be a big "snappo!" if you get something bigger than hammer handles.
