I have 40 series crimefighters and they don't offer much grip. I also have badlands that I haven't put on my truck yet, but they look mean. I also have Mulchers and man do they grip! The crimefighters tread is too small. I'll have to put the mulchers on my truck and put a picture in my gallery. If you are looking to bash and crawl the Mulchers would be the best in my book.
