there ok. too light for spreader bars.
get aftco roller trollers.
crimp a foot of heavy mono on them and hang them off the stearn cleats or the trailer tie down loops. if your looking for flatline clips.
#64 rubber bands work just as well

Yup flat lines will be used. was gonna run some different baits off them down the middle.

Black clips are the best IMHO and I use them but for flat lines I use rubber bands like posted above.
