If you only want a bull, any bull, then Bauer is right. If you want a whopper, use a herd bull diaphram. A herd bull won' t bother with puny bulls, he don' t feel threatened. He' ll come in for a big bull though. Now you don' t wanna scare him, jus' get him good an curious. Big bulls will rarely come hard to a small bull call. Once you get in their discomfort zone and sound like real competition, they' ll come stormin' . The keys are get close enough to matter, and be big enough to concern him. If I really want a bull to come to me, I sometimes mix in a cow call or two with my bugles so he' s got sumthin' to fight for.

Okay, so it took 2 paragraphs. Wish I knew thet much bout the stock market, an' I wouldn' t have to winter huddled ' round a pot belly stove eatin' jerked elk an' meltin' snow fer my coffee.
