I always bow to a jumping fish because the breaking strength of leader is significantly less out of the water than in the water. I believe that water acts a somewhat of a shock absorber. When a fish reenters the water after a jump, I have seen many leaders snap. I generally use fairly light leaders (usually 8lb. test) so I bow and have never had a problem. Just my 2 cents.
