OK if you haven't figured it out yet its a combination of a couple of factors personal preference, legal methods and traps, brand, ect...... in CT i can only use 10x10 in water frequented by beaver and all body gripping traps have to be completely submerged except 110s .... some times thats impossible. Then you add in the otter problem my ottter season ends March 15 my beaver ends March 31 after the 15th I have to slide all triggers to the side so I don't get an incidental catch. Then do you get round or square do you buy Duke, Belisle, Bridger, etc. You'll find your preference. I have everything round square $5 used dukes to $35 new belisles. Its trial and error i will say this watch Craigslist and go to your local club meets make friends and they will help you i have loaned out my Comstock cages to guys thinking of buying them or to help them out this is a good community talk to the old timers in your area they will help you work this out.

If your in southern Indiana the guy that makes the rbg is located in Holland. He has other traps, lures, stretches and such also.

I'm new to trapping but used Bridger 330s and 280s this year. The Bridger 330 seems to have disproportionately small spring eyes, smaller than other manufacturers as I've read. Was kinda a pain setting. I will probably buy a diff make for this year. I liked the 280 seemed more proportional and we'll built to me, caught beaver and otter with both, spots where the 280 made more sense and spots where the 330 did. I'd carry both if I could.
