If you want to use the DDC electronics and have the full adjustability, I can do that for you.
If you want the Ohlins and turn off the DDC electronics, I can do that also.
I said that KTech rebuild the OEM DDC rear shock. It would not be a KTech replacement. They one of few that even offers the service in the USA.
As to experience, I put the DDC to the full test on my 2015. I had GPS by corner, and has real time suspension adjustments via RCK3 software. It take alot of work to get to that point of the ECU controlling the DDC. I never did DDC on my 2018, as I decided to start it with the Ohlins front and rear and never did put the DDC back on it.
You still have not outlined your actual goals with the bike. You want to street race on curves, or road race on closed course tracks, or drag race on track, or roll race on the street. There are many applications I help setup for people.
