Hi Bruce,

The interior space in a Stratos is critical, as you've already guessed.

The differences between a Hawk and other replicas in the interior space and seating positions is not slight (in Stratos interior space terms).
The LB STR has a horizontal floor in the seat mounting area, and the interior space is greater. Not by a lot, but a significant amount.
Small differences between the interior space of each Stratos replica will add up to a lot.
Sitting in a Hawk will not give you a good idea of the interior space of an LB STR.
