Well I"m going to go against the group and vote for the weathershield. I have had no issue with mine and when I compared it to my TC Pro Hunter SS for cleaning, the weathershield won hands down. Nothing seems to stick to it. As for which one will be easier to find different barrels. I dont know what to tell you. Kinda depends on TC. If they really get into the weathershield they maybe easy to find. Right now its easier to get SS hands down. When it comes right down to it, either way is a win win. Just going to depend on what color you want your gun to look like.
