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.
