I just changed my beater on my dw 5000 from the orig. beater to the new style dynamic beater.
The beater is dynamic the harder you use it, the beater a like a hard plastic or wood sound the softer you use it it has more of a soft wool type of sound with the adjustable weight it works well for me since one of my 4 piece kits has a 20" bass drum & my other 4 piece has a 24" bass drum which makes it play the same which can be a issue from switching from smaller bass drums to larger bass drums.
I recommend it strongly,
