Hi William,
I started small and now make appx 100lbs a month for familly, friends and now friends of friends and friends of familly !!... All in various flavours, in Pork, Beef and now do Venison and Venison/Game.
I would start on natural hog casings if I were you. They only downside as I see it (apart from the dreadful smell !) is that you have to untangle the damn things and cut off managble lengths before you soak, then flush out with clean water before you use them. With the Collagen, all you have to do is open the packet and use, but they are much, less forgiving when it comes to slightly overstuffing and teaching yourself how to link properly, and can "ladder" like tights which sometimes means you have to pull a bit off the stick and cut it off.
That being said, my local butcher where I buy my meat from makes 7 tons yes 7 TONS ! of sausage a week and only uses Collagen, his machine just spits out linked sausages and at a rate of knots !, hand linking though is a little different !.
So, my preference is for natural casings, but I have used both with reasonable results....
For instance, the following were my very first attempt
These were with Collagen, as you can see it didn't go as well for me 1st time around with the Collagen, they looked OK but could have done better
I have come a long way since then (note to self, need to upload some new pics !), so at the end of the day it's about personal choice and for me, ease of use, and although the natural casings take more in the way of faffing about, I prefer the ease of filling and linking etc, not to mention the "bite"...
I use Natural Hog size 34/36 by the way, (

Hope this was useful !...
