I am a very green new trapper. I have different sizes of conibears and tried the rope setting method described on this site. I could not get enough leverage to get a 220 set. I know i am just overlooking something but can't quite figure out what it is. Any suggestions?

Make or buy some proper setters.

That was my next move just wanted to make this work as well

Good strong bodygrips are a bugger to set by hand. If I didn't have XXL hands and long fingers I couldn't set them either.

I used to set any of them. I use the setters now.

I can set any of the strongest by hand no problem,but who wants to do that all day removing animals from traps when there is a tool that makes it so much easier and faster with no risk of damaging the critter.
The rope is handy as a safety device only.

I shall venture tomorrow and buy a set. Thank u everyone!

Call me a sissy if you want, but I have a hard time setting #110's by hand. Certainly not #155's or #160's!

You will completely understand once you join the connibear club.

Same here...strong 220s are a bugger because the spring loops are quite small.
