I also ordered a csl dd last Friday, I was sat on my ipad when the email came through on the 4th and immediately went to order, the website was broken for an hour or two, I just kept trying until it eventually let me checkout!.
I’ve already got a csw v2 wheel base so not expecting night and day but it sounds like it should have that bit extra fidelity..
I just checked my emails, my first fanatec wheel was a 911 turbo S in 2010 with club sport pedals, The wheel became faulty after a year, they sent a replacement, then a year or so it went wrong again, so the swapped it for a CSR Forza edition, that went wrong, so they replaced that, until finally I got a good wheel, I was quite happy with their customer service, so in 2015 bought the CSW Wheel base and universal hub (now on an Xbox unvisersal hub), and now fingers crossed a csl dd...
in between I’ve had Thrustmaster wheels alongside but keep going back to fanatec, my original club sport pedals are perfect 11 years on!
