If I was fishing the Kawarthas I'd probably pick up something in the 8-9ft range, med heavy at most. You don't need a pool cue for those fish and it's way easier on you casting big baits all day. My fav rod is a 9'6 telescopic MH Legend Tournament. Makes figure 8s a breeze and loads up and helps me bury hooks. Along with all the rods/reels/lures you need to make sure you've got a proper net and release tools (Especially hook cutters), jaw spreader, etc. Handling these fish properly will have the biggest impact on them going back unharmed.
