Galanie, LOLOLOL I had the arduous task of making sure the Gin was gone before I used it for the mother cluckers... I'm self sacrificing.... LOL
@ Blaze.... Remember you always have to have a hole i the top of the bottle or the nipple won't flow... just creates a vacuum
I have never had any problems with the screw in type. I also use plastic bottle. I drill a hole in the cap and a hole in the bottom o the bottle. The nipple goes in the hard plastic cap and I put a bolt through the bottom and hand the bottle. I'll illustrate with a couple of pictures...
