UFB is under construction in my street and should be weeks away from being available to order.  
It would be easier and I'd be happy to stay with my current provider Slingshot, but they are not listed as an RSP in the TRON according to Ultrafast Fibre.

Will i be able to sign up with Slingshot in the coming weeks once its available at my address?  Also would I need the Slingshot $20 router as I have a Linksys WRT1900AC which I'm sure will be better?
