Thanks guys for the info.
I'm gonna order the 5,4 and the 4,5 Atlas. Between them I have an older 5,0 Combat.
Also a reason for not choosing the 5,6 Combat is the almost full extended mast base. This might not be an issue for bump and jump, but in waves after a fall I think it is a problem. And the 5,8 Atlas (actually my favorite) unfortunately needs a 430 mast. For flying with airlines weight reduction is an issue and with 4,5 A, 5,0 C and 5,4 A I need just two masts (370 and 400) and not three. Max weight "should"

not exceed 32kg.
All three sails fit into one boom (X9 160-220).
