Mahogany is also a lot heavier than cedar and not as tolerant to bending.
Strip composite uses the strips as a core and its strength depends on the
core maintaining its shear strength. Cedar can absorb more deflection from
pounding.

Mahogany would not be my first choice since it is much less rot
resistant than cedar as I understand it.
