How much would it cost to retrofit an Otter with those 4-bladed props? I wonder if Kim Gibbs would be willing to pay for it?

The slider heats the entire length of the lines as it descends at high speed during opening, and does it repeatedly jump after jump. Heat shrink tubing, on the other hand, is only applied to a few inches of the line at the bottom, and the heat is applied just one time. So there are differences in both time of exposure and the amount of line affected.
