Neither one really,
The #3 coil will bust his leg and the #1 long spring is a bit small.
I'd say a 1 1/2 double coil. You have the strength to hold him without busting his leg and double coils are easier to conceal then a single spring.
But i'm not a trapper longbeard there will be plenty along to correct me if I'm wrong /ubbthreads/images/graemlins/wink.gif
