I am hopeing to get some permanent tunnels made this Christmas for stoats and weasels. I might use a mk6 in the permanent tunnels
6s are ok but hard to make a nice perminant tunnel for and i dont think they catch stoats and weasles as well as 4s, but were you are you will pick up a few rabbits (from memory ) get some old clay drainage pipes they make nice invisble tunnels dug in right, you will have a lot of eyes on your ground
I just want to use mk6 because i havent used them
