Hello Agrelon, ~1.5 sqm gap is generally OK for sails bigger than 6. In small sizes you may appreciate 0.7 or even 0.5 gap. Moreover gusts make it difficult to sail overpowered while it can be pleasant in steady wind. With your current quiver you have little or no overlap. If you go for the 5.2 you will probably not regret it.
