I´ve fooled around with a few pedals A Premier, Pearl, Yamaha and two types of DW, and the cheaper DW does it for me, a 5000AH with the chain and offset-middle drive. The other DW was a newer model with a double chain and weights.
Well it was pure labor, using that one and when I added those weights, it was so slow coming back up. But the cheaper one is pure gold, fast, light (I allmost dont use the spring tension)and natural.
