Don't take this the wrong way - but after running leagues and not charging for all the times etc admining doing them (Season 1 UFBR almost cost me my job) etc etc
I also seeing the effect of eTM with charging last year I'm very wary.
I also don't like the idea of 'not contributing' when others do. This is a classic thing which almost makes the 'not contributors' feel guilty - which I would certainly do.
As a net effect I would like to withdraw my sign-up to this league.
But you have a compulsory pitstop where you can either change tyres (meaning compound or just the same again) or not
With the rules stating the R1's on ovals only and on normal races 1/2 only I think this is good enough. I do not think that you have to use BOTH types in the race.
You have to stop - but it's up to you whether or not you have to change tyres - therefore meaning 'stratagies' and 'driver tire saving ability' comes into it - otherwise everyone is doing the same thing - and then there is no benefit for either extra practice, setup sessions or good old fashioned racing luck
