I Had a pushed DHX coil and then went to a CCDB and there was a big difference.The CCDB feels like it is making the rear wheel stick to the floor,you can also play with the LSC to get the perfect pedalling ability.
If you have any problems with a CCDB speak to Malcolm at cane creek,he sent me a spring and mounting kit FOC,and advised me on some setup.
I have heard good things about the Rockshox Vivid but havent used one yet.
