1: Put flour on the inside of the sliver you are sliding over the bladder. This helps it slide.
2: Put a rod or piece of piping in the bladder when performing the colossus. This helps it maintain shape when you are wrestling on the pieces of innertube.
3: Don't use little pieces of innertubing. Use pieces slightly smaller than the bladder, from the bulb in the bladder (spot where it is bigger), to where the bladder gets pinched off (the end with the orange stripe on some soakers). It is actually not that much harder to do, and looks way better when you are done.
4: You don't have to hack up the pc. You can use a small screwdriver to work off the cap at the end, then slide out the bladder. Then, when you are done, you can put the cap back on if you want. I wouldn't, because you can actually hold a little more water in the pc now.
Thanks for taking your time to read this!
