I've baited up with bait that is still warm after rolling it. As you say, you don't get any fresher than that.
As for a gun and better rolling table it will make your bait making so easy. When I rolled bait I could do 60 eggs no problem. In the end I used to crack the eggs into a Bowl and blend all the flavours etc into it then store in the fridge over night then mix, roll and boil the following evening. I had a little jug that I'd scoop the liquid up in, pour into my bowl and that needed exactly 3 scoops of powder and that made enough paste to fill the gun. I had the big tables, an air gun, burco boiler and you can knock up a lot of bait in a short time. I reckon 120 eggs would have been possible if I'd had wanted to, with another pair of hands then definitely possible.
