X and Polywad disk = two different methods. Each has its fans. My shooting buddy swears by the X. It goes in the cup before the shot. Polywad you insert in the wad station after the shot and the one I prefer.
I am not sure it makes a lot of difference or more likely can't tell the difference without extensive testing . Thing about the disk on top I have confidence in it for certain targets. Confidence is 90% of the game.
Side tip I load my regular 7/8 loads I Red AA hulls. Spreaders in Green Gun clubs. Keeps things straight in the pouch. Much as I like 7/8 I do have a few 1oz loads in STS hulls for very long targets. On the one hand you can make the game too complicated. On the other loads tailored to the Gun and Target are nice to have.
