REFLECTOR: Nose Fresh Air Vent

[Brooke Wolf]

Does anybody have any thoughts on the necessity or advisability of a  
NOSE fresh air vent in the XL?  Does the overhead plenum provide  
enough fresh air or is it a good idea to have the additional one  
coming from the copilot side of the nose?  I never could figure out  
why we have both!  Is there another use for the vent air coming from  
the nose?  Before I cut another hole I thought I would poll the  
group.   Any advice would be appreciated.

Thanks
