I don't have one but everybody that does seems to love them.
Excalibur decided to discontinue the Matrix 405 and the cut down the rails to make them 350's, a non-catalog item.
If I had any other Excl other than the "big" bows I have, it would be a 350SE/LE.
Go on Google and Google "Excalibur 350 SE" and you'll find plenty to read.
