I can live with the longer brake pad changing time, it's not that much of a PITA.
It depends. I went through a set of PF01s in 2 weekends on the OEM brakes consisting of 20 minute sessions. If you consider that being able to withstand 30 minute sessions, then OEM brakes will work.

I don't. I think the OEM brakes can't handle the horsepower and weight of the car which is evident under threshold braking. But, OEM brakes with track pads and good fluid will work if you manage the brakes. Meaning you don't drive the entire session 10/10ths.

For 30 minutes sessions...the brakes will be the least of your concerns. Cooling will become your top issue.
