I am debating what line to use for pike this spring. I troll with 20 lb mono but I am wondering if I should use superline to minimize strech. What have you experienced?

i dont think i will ever go back to mono for casting cranks& jerk-baits. i use a couple brands of superline. fireline for walleye & power pro for muskie and pike. im trying the new fireline braid on one of my muskie rods, its not bad dose cast alot better on the bait casters then the standard fireline. just remember when you are using super lines  they have no stretch so think about the next week link that is what will break. also make sure your rods have hardened guides cause ive seen superlines cut groves in them. another thing is back it with mono or wrap some electrical tape around your spools to prevent it from slipping.

I have 20lb spiderwire on a spinning rod (ugly stik) MH tie a clove hitch knot and you won't get slippage. I troll with that rod. I have 40lb spiderwire on a Pete Maina baitcaster ugly stik musky rod. I use that with live bait. I also set the drag to slip if I snag something like a rock and stump. Its my first choice when it comes to pike and musky.

I use Fireline and PowerPro almost exclusivly, although I am trying out the Stren Microfuse on one of my rigs. I'll post when I have enough experience with it.

The only real problem I have had with the fused and braided superlines is that they don't like to hold in planer board or downrigger releases. Considering that half of my fishing time is spent trolling Lk. Michigan, this is a real concern. My partner and I have found that securing the line to the release with a rubber band(use the ones sold for this purpose, not the ones in your desk drawer!)by half-hitching the band to the line and then clipping the rubber band in. the release works well. If you are pulling a large bait, it may take two bands.
