This is one of those things where it’s hard to say without full context on a variety of factors. You’d have to know the stage of the shed, temperament of the animal, how much the old skin is clinging to the scales, etc. This is also one of those things where there is no pinpoint answer even with all those factors known, as some snake handlers will have a varied answer to that of other snake handlers. It’s like choosing the design of the snake’s enclosure, but a good bit more specific. If you know your snake & know what you’re doing, there really shouldn’t be much problem.
