Don't be so quick to throw in the towel there. The combonation of a mouth reed and grunt tube are the way to go. When perfected,your sounds are much more realistic, you'll be able to make all sounds by both bulls and cows, it's worth your time & effort. There's no real external mouth reeds on a tube that compare to reeds in your mouth. Most sounds out of the horns have human written all over them. I'd at least do some more practicing with them since you can turkey call with them. In the long run you'll be happy you did!!
