Around here we use 2oz weights to keep from having to have so much line out, and drag a fish in over so much distance.

A long handled dip net is good to have, too, since some use rods up to 20ft long for pushing cranks.

Many use line counter reels with braid, then a swivel, the trolling weight, then 5ft of 6lb test mono, a swivel or clip & then the crank. Since you can't "stop" when a crank gets snagged, you just sacrifice the crank to the timber troll and keep on going. Speed is generally ~1.8mph, but sometimes in the turns you may get hits on the outside crank (going faster) or the inside crank (going slower).

I'm not equipped or set up for cranks, so I mostly cast, spider rig, or push jigs ... so all the above info is what I've seen & heard of being done by my crank pushing/pulling buddies.
