Good observation. I wasn't aware my post was misleading until I read your observations.I have to answer on this about the OSW, because it is so misleading.
1) Which company are you talking about? Because Tomo from Simracingbay is quick and helpful in everything you need. Spare parts or help.
2) I do not think that you need any lesson with Simucube software at this state. Just download the software and update when need it the wheel. It is pretty straightforward like the Fanatec control panel, but you can fine tuning a lot more options.
3) Never had oscillation, probably because I take 2 hours to set up the wheel how should be in iRacing.
I had many more issues when I was in Fanatec Ecosistem. With Simracingbay, SRM and Heuskenvield I have found a better and faster support, but this is my personal case. I only keep their rim and never look back.
I was actually talking about Sim-plicity.
