<{POST_SNAPBACK}>Yes I agree, their website can at times be very misleading. It is possible that they are currently out of the normal 3.5s and are pushing the 3.5 XLS.
If you look on the left of the sWd website, you will see a list of web pages.
Click on Products, then loksond. It explains the chips there.
I would be surprised if they were out of them, they usually have one delivery a week from Germany.
The XL is for larger motors up 3.5 amp i think.
