Should've said that this obviously assumes a weight integrated setup - with
a weightbelt a smaller wing would be adequate.

A couple of other things we learned from the Halcyon people at DEMA:

The 27, 36 and 45lb Pioneers are all the same physical size, just different
sized bellows to allow them to be inflated wider. Hence the extra drag in
the bigger lift versions is minimized - what a great design, as usual.

You say you recently acquired your SS back plate. If its the new-style
Halcyon one with the tank band slots then you don't need to buy a single
tank adapter. The new Pioneer wings have some clever gizmo built in that
lets them be used directly on the new-style backplate without an STA.
