if your just starting out, I would stay away from the egg trap. they are a pain to use, you need special tools to set and remove the coon from them.
If you need a dog proof trap, I would go with Lil' Grizzes, they are the best dp out there. if you don't want to spend a bunch of dough on traps and you will with any of the special made DP's out there, I would get some Duke 1.5's footholds and use them, coons are easy to trap and a good thing for a beginner to start out with. if you need any other help, just ask, I'll gladly share my 35+ years of trapping experiance. good luck and happy trapping.
Tac20, nothing person too you, but I wouldn't recommend Trapperman to any new trapper. that site isn't what it was 5 years ago, now its just a group of wannabe's that think they can trap and bully all new trappers that ask questions. Trapperman is the worst site for any trapper to visit let alone join.
