if you would like, in order of preference, what I felt could be improbed
1 - Rostrum needs to be a lot higher, this could also then be converted to more under cover pit space - reason - with the track on a slope, there were certain 'flat' areas that, due to the low rostrum height, you lost all depth perception.
2 - ruts, now I know from COBRA, you not got the manpower to do it, there isn't much you can do, but if and when you can, you need to rotovate and then roll, as the 8th scalers just ripped out all the hard work you had done, to patch the track
3 - Jump Profiles - they just need a smoother upramp for them, and then they would be a challenge and not a 'luck' thing.
On the positive side, it is good to see a club trying to make the changes, and that is not to be sniffed at, so you got to pat yourself on the back, got a good venue there, and if you listen to what people are suggesting (and I am sure you guys will), you can have a cracking venue.
Just a little foot note, for the electric cars, having to drive up that hill, really heats up the motors, diagonals and switch backs would work a lot better, as you would have the cross slope challenge too.
