SPA Info Requested

Thinking about attending the 2016 F1 race in Belgium (SPA) for the first time. Wondering if I can get some info on the best seats to purchase. Just looking at the map Gold 6, 1 and 9 (turns 19, 20, 1 & 2) seem to have the best views of the turns, but, that's just looking at a map.

Like to have someone give me info on what they believe to the best seats, Gold, Silver, Bronze and where to see the best action.

Any other info would be appreciated as well.
