Worth noting too, that using your road tyres on a trainer will mean that any little bits of road debris will work their way deeper into the tyre and potentially cause a flat. That's what happened to me. I think the extra concentrated pressure of the small roller against the tyre causes the problem.
Nowadays I have a Kickr after upgrading from a Kurt Road Machine and I definitely won't talk you out of a direct drive smart. BUT my primary concern is high torque track sprint training. I had to wrap grip tape around the Kurt roller to stop slippage. If you aren't really that powerful then I honestly don't see s need to upgrade from what you have.
