Neck Reining w/Full Cheek Snaffle?

Can you neck rein using a full cheek snaffle? I just recently got a 15 yr old Qtr Horse gelding that has a very soft mouth. I am old school and am more comfortable neck reining. I have an argentine snaffle and a full cheek snaffle. I have no problem purchasing another bit but I was wondering if I could use the full cheek snaffle with bit keepers that I already have. I am not very knowledgeable about bits so any advice would be appreciated. I have also heard that full cheek snaffles can be dangerous because the ends can catch on things but I have bit keepers so I am hoping that would eliminate that possibility.
