i really would not recomend useing any long shank hook in barbless due to the nature of these hooks they will move about during the fight and without a barb to anchor they they will cut into the mouth causing damage not a good idea
if you have to use barbless go with a wide gape pattern with an inturned point my choice would be the fox hooks these are less likely to move about and will cause less damage.
just my opinion but barbless long shank hooks are a no no
