Well, i tried it out. These pieces just didn’t do anything better than what i’m currently using. I’ve got a 101 and 104 rim G cup and H cup and G8 and H8 shank. All LT, and not the best condition. Not bad, but some nicks here and there. Got these in a trade deal, so didn’t shell out any cash so probably could let go for a pretty good price. Email/PM for pics and send me an offer. If you’ve got a nice euphonium case i’d like to work some type of trade plus cash for that, also looking for 114 rim (preferably gold plate or lexan) K cup and K9 shank.
