Janis, you should consider the tracksize. I know what tracks you have in mind as I can guess where you are from
On the flowing tracks that are only "a bit tight" for 1:8IC electro would seem much slower than GOOD 1:10 nitro.
Anyway, on those tight tracks that we are racing in baltic states (and other eastern europe countries also) 1:10EP shows comparable laptimes.
BTW, i remember Pro10 used to be slower only 2sec than 1:8IC in average size track in Poland. So sad this class died...
