hi there.   yes, you can use the X series seat and make the conversion.  it works great.  the standard seat on the 2210 is awful.   get an X series seat and you can install yourself.  you might have a problem fitting the bolts, but should be able to adapt with no problem.  I think there are some photos of conversions on this web site.  try searching and you should find what you want.   I put an X on my 2210; took an afternoon, mainly just getting things lined up.  made a huge difference.
