A properly setup L10 means that you will not chop paint at all.

While knowing if your paint was breaking in the barrel because of roll outs, brittle paint, loader failures(the loader not keeping up with long strings) and the classic chop. A L10 will eliminate the chops, and will be gentler on paint, overall.

As for tips, there are a couple of L10 setup guides, but start with the smallest carrier and go from there. Make sure you have air to test it, and after that, enjoy.
