Thanks Marv for the Legend referral.  I checked with Jeff Ackland who is
using a reversing prop on the turbine Legend.  He says that he rarely uses
the reversing prop for braking, and when he does, it is at higher speeds
right after touchdown (80 to 50).  The only tricky part is if the airflow
to the rudder is blanketed then directional control is touchy.  What he has
found that works extremely well is to put the prop into flat pitch upon
touchdown making act as a rotating drag chute.  Another Glasair II builder
has commented that his plane will decelerate from 200mph to under 100 mph
just by moving the his large 3 bladed prop into flat pitch. 

Conclusion:  Reversing prop not necessary to feel good about going into a
2500 ft strip.  However a prop capable of going into flat pitch is very
desireable and will act as a large speed brake.
