Anyone use an Incra Fence on a SawStop with 36" rails?

I'm making preparations to buy the saw for use in my home / hobby workshop. I think I am going to get the incra fence, but I have some questions about compatability.
  • Model TS-LS, TS-LS32 or TSIII? Which works best?
  • Did you simply cut down the 72 inch Incra rails?
  • Does the fence reach across the table front to back? Specs suggest 28" table, but SS is 30" deep.
  • Do you use a router table on the wing?
    • Do you reverse the fence? Is that practical?
    • Do you recommend mounting the router in the SS extension table?
I'd appreciate any other suggestions or comments.

Thanks, Bill
