I picked up some tubed 24-26 sheep casings from Syracuse casing a while back and finally tried them out today.
Very nice product, very thin and clear, and I love the the fact that they come tubed. had 1 blow out in 5 pounds which was no doubt my fault and not the casings.
Just a heads up if anyone was interested, their prices are a little higher then B&P but I think the quality is better.
