Right I will try and answer all questions in one post
Pinks springs are one softer than red, they feel soft static but it all depends on how they feel round the track and 8 out of 10 times the pinks are better, the reds just tend to make it jump around a little too much at the rear.
I have only played with ae shocks a little and to be fair I couldn't get it anywhere near as good as with the losi so not dead sure really. They were better landing the jumps but just made it understeer on power really badly and were not so good round the bendy bits. I always run the black front spring unless I need more steering but outdoors I don't normally need anymore. Black is not too hard, just a touch harder than ae blue I think?
I have only tried the roll bar outdoors once, it is there just incase I need some steering!! I use it at Worksop but I won't be starting with it at Kiddy.
I use the kit wing, moved forward and low and cut round the tower and with no gurney. I have tried a few others but tend to go back to this most times. I do run a front wing as well though as it helps on the jumps.
