Zulch, in my opinion the Slix-hot nipples are well worth the money. They are very consistent in size/dimensions which a lot of factory nipples can't lay claim to. Also the Remington #10s are the closest thing to one size fits all and when they become available again are worth laying in a supply if you intend to do a lot of shooting. My only concern with the Remington caps is just occasionally the green priming compound will fall out of the cap in the form of a disc. All this is not news as I'm sure you have heard it many times before.
The push stick I thought I needed at a Cowboy Shoot in order to insure ignition. I guess I'm too heavy with the stick and went back to consistent thumb pressure which I have a better feel for--just make sure the caps fit correctly.
Hope we haven't strayed too much from Hawg's water test as that was quite interesting.
