It comes down to personal preference, but most experienced guys seem to like one piece rods from what I have read on the subject. Some guys will tell you they would never use a bore snake, and some swear by them. It also depends on what you are cleaning, I use a bore snake on my 12 guage, but would never use one on a rifle or pistol, just my personal thing,,lol, I have nightmares about snapping one off in the bore

You will read many different opinions on what is right and what is wrong, in the end it will come down to what you prefer yourself, you will find the same problem with asking about which cleaning product to use and which lubricant lol.
