I degreased the internals of my HW30S almost immediately after I bought it years ago. It too had some twang, bug after degreasing it, the speed increased by 40 ft/s and the twang was completely gone. All you hear now is a nice ‘tok’ after you pull the trigger. It’s about as backyard friendly as you can get, when it comes to springers. Taking it apart is also easy.
