I would try more of an off-beat chop if you want a straight ahead bluegrass feel.
Otherwise try something a little funkier and syncopated.
A rhythm like: 1 (and) 2 and (3) and 4 and
Don’t play the count in the parenthesis and you’ll get a cool syncopated rhythm.
Ultimately it’s personal preference, try a bunch of stuff along with the practice tracks and see what you like.
If you have more questions let me know.
