Hey Brendon,
re the anti lag launches I found the same thing with my RA. Much better out of the hole with it on. I set up a press button on the steering wheel I could reach with my thumb. Turn antilag on for launch and then just take thumb off to turn it off. If rotational idle kicks in your not trying hard enough!!
Was also good at the end of stage to give the button a quick press to kick in rotational idle to assist the cool down.
Have to come and cacth up soon as I am toying with making a purchase.
