F1 how too improve it

[sumo]

I am a marshal at silverstone, and whilst on post this weekend at the F3/GT meeting the topic of conversation inevitably got round to F1 . As well as the general opinion that it is boring , the question was asked how can it be improved so to speak . The most popular view was that either (1) bring back turbos , full areodynamics and big fat slicks (2) as above but with ground effects not turbos and (3) all the above and limit pitstops to 1 per race and that for either tyres or fuel only. I look foreward to read other ideas from you all.
