I use it for a month.
I had a DW 5000 (single) and DW 9000 (double).
It's sturdy as are the high-end DW. (I do not know the other end DW)
It is soft and very quiet.
Me I relax the spring (voltage soft), and the response is quick. I play toe, but also flat pedal responds perfectly.
The 8000 (unlike 5000) allows the setting "accelerator" or "turbo" that qualifies the attack on the channel guide .. it's subtle but it feels underfoot (my personal settings is "turbo").
It is a financial investment! But mandatory if you look at it in time ... so for me the quality dosh!
Small flat plate is the "Diamond Base Plate: This is only the aesthetic mouaii bof! rather suddenly, the red plate ... but that one is in the detail.
DW in the range for me is the best choice so far: The setting or turbo accelerator included (unlike the 5000) with the flexibility and response game, equal to 9000.
Finally I tried a few times the Pearl Demon drive: Very good pedal but transmission "DIRECT LINK" (arm), bof! impossible to explain, I'm definitely addicted to the chain drive .... and I have no shares in DW .... Alas indeed
