Gags tend to have far too strong a spring and it can cause damage to pike,Gary turning the fish upside down won't help as he cannot hold it in that position and remove the hook,we used to blob araldite around the business ends of the gag to stop the points causing damage,if I wasn't confident unhooking a pike I would not fish for them,or use methods prone to catch them,also,if I thought my methods would cause real damage to bi-catch such as pike,I would not use those methods,no matter how much I enjoyed them,that's me though,others think differently obviously...
