Legroom comparison question...composite vs aluminum shell seats

We are trying to get a little more legroom in our car. The cage and supports are in excess of the Chump minimum, so it would be very costly to try and modify.

 

The logic is that we can go to a 10-degree lay back, aluminum shell seat (Ultrashield or Kirkey) and pick up some leg room due to the thinner shell. Might also gain a little room with less lay back angle. 

 

Thoughts or comments? We're a little on the fence about investing ~$700 into a seat only to find out we gained nothing with it.

Less layback on the seat then raise the front of the seat up.  Gives the feeling of more leg room.  

Yea, we had a 20deg. layback and I hated it.. we now have a 10deg layback but it is in more of a reclined position... much much better

That's what we've been thinking...10 degree lay back with an aluminum shell. It'll pull the front of the seat up a bit, support the driver's legs and give a little more distance to the pedals. We're also modifying the front crossbar to lift the column slightly. 

Was just wondering if anybody had experience in using both a composite shell and aluminum shell seat.
