How about no straight at all????
Well not quite, but a few shorter ones, maybe 3 in total on a track? Not really seen taht done many times but as long as there's a decent area of the track to run a start grid from, do you really need a long massive straight at every track??
Personally i always prefered having a straight at the back with all the corners and tight sections closer to the rostrum as over-taking etc can be better as you can see clearer.....
Tracks with a raised back section though like Stotfold are ok as you can see the back areas nice and clearly anyway i guess.
