An 8wt is fine as has been said. I use a 7wt for smaller river Pike and a 9wt for large Pike & Muskie.
As said bring a sinking line or shooting head in the same.
I like Tyger wire for a bite guard.
You don't need really big flies a 2/0 5"-6" Deceiver with a flash tail is good along with a waker hair bug or gurgler for top water.
