Considering boxes for skunk, For those with experience. My state a 5x5 is the largest body grip on land. I believe a 120 will strike them better behind ears, but I like the idea of versatility of the 155 for log crossings for mink. Your thoughts.

I ran both of these traps this fall in Newspaper tubes. I had mixed results on spraying, Seemed to be luck as much as anything weather they sprayed or not?

The belisle 120 is a phenomal trap to work with. The bridger 155... Not so much.

In my experience, I prefer a 155 or 160. Skunks have small and seemingly hidden windpipes. A 120 makes a great neck catch but the skunk doesn’t always expire quickly. I found that I have less sprayers and quicker kills with a suitcase catch that’s more consistent with a 155 or 160.

120's for the skunk size we have here in WNY
Dead at the box. No spray, no struggle

We are limited to 5x5 here also. I prefer the 155s. I have mostly been using the CTMs and really like them but I like the Dukes OK too. The skunks don't spray and I pick up a few coon .

Neither.

Bridger 155s are junk IMO
