I go for ST with both feet these days. I drop the 1on1 SA and seem to do better because I play short possession and never counter attack. I notice I rarely get 1on1 opportunities and even if I do my ST always feed my AMC. I think your ST needs a ST partner or an AMC to link attacks because your formation is congested in the back and the only way to feed your ST is making him drop deeper or long balls. Usually the teams with ST as top scorers play with more than 1 ST.
