We went to roller bearings on all axles to reduce drag on the diesel mechanism. The earlier engines suffered from too much drag and this solved this problem with what I saw as dramatic improvement.

True, if axles are not aligned with the bearing it makes things worse, but since the trucks are die-cast the geometry is very true. The small amount of equalization from sprung journals doesn't seem to bother the overall effect. 

As for the QSI or a plug-in DC module. You are right. It's cheaper to just give everyone the same system, the same wiring harness, the same everything. We did offer our F7s I think with or without DCC and we had 5 takers for DC and 195 for DCC. So even if people aren't going to keep the QSI system in their model, they want it in there perhaps for re-sale. So we stopped asking. The factory does a lot of QC while making these models, and giving them different variations of the same type model confused them and us. So we try to keep it as simple as possible. QSI is a robust system with great sounds and features. We have very few failures after delivery. As for support, we handle that.

Keep having fun...
