mixing and matching wings

[edt]

I'm ready to graduate from the low aspect wing to a medium aspect wing. Do you really need to buy a new rear wing and front wing? For instance can I just buy the Happy front wing and put it on my beginner Rocket fuselage with the Rocket tail wing? How much does that rear wing matter? I want more speed, so if it turns out doing this really reduces my top speed I'll buy both a front and rear. Thanks. I also sometimes wonder if you can just ride two of these rear wings as your front wing some kind of double rear or the converse two front wings for a double front wing configuration (assuming you do the necessary adapter mods).
