I am running a TBM 23x8 classic beechwood prop on one of my DA50s. I break my 50s in on 22x10 TBM props. They are very economical before you switch to a more expensive wood or Carbon fiber prop. The TBM props are a little soft and a little louder than some of the other wooden props but they come fairly well balanced and have done a great job for me!!

Good luck...
