I use the knurled fitting on my hybrid which has schrader valves to stop the valve from disappearing as the width and depth of the tyre doesn't keep the valve in place at lower pressures. It is not a problem on my road bike which has much narrower wheels. You should find the same.
OK cheers mate, so glad I found this community as everyone is so helpful.
