R stand has good cheaper seats coming onto the main straight, u can see all the way up to the casio triangle ( think prost senna )) also on the back section, after turn 2, cars get good speed and u can see up through the “S”s…..
Ps the main stand virtually only gives u a limiited view of the straight and across to the pits, plus its facing direct west so come race day you will be looking straight into the sun…..
