For my bench I don't use a kit. Like Mountain Man I use CLP, I have a series of one piece rods I all sizes with guides and multiple brushes and mops for every caliber I can find. In each of my tool boxes I have an old M-16 cleaning kit old school not Otis. Then a small Plano box of brushes , adapters etc. with a small bottle of CLP. I found I was not a one size fits all sort of guy.
Keep up with the trends, avoid the fads, take your time and do work you can be proud of always
