Be cautious about treble hooks if you are going to do catch and release , sometimes the treble hooks rips their mouth up . I cat fish and will catch a carp once in a while . I have started cutting one hook off the treble to minimize the damage on the fish when they are undersized .
Agreed with this ^^
If you are fishing in an area you know has a healthy concentration of buffs you can use a simple small Gamakatsu hook with corn. I usually use size 6. Set up your rig like a simple Carolina rig. Worms also work well for buffs, but I have had best luck with corn.
If you want to simply try and chum up a spot, I will typically poor quick oats in to a large freezer bag, pour in 2 cans of cream corn, mix it up really good and let it all soak in. When you get to your spot, roll up your chum to the size of a golf ball or baseball and throw it out. Then cast out your bait and you should do well.
