I have an old calf head on a flesh hoop that seems to be in need of some stretching out. It'll fit on my modern Sonor floor tom, but not my slightly out of round '60's Ludwig. Would it be best to put it on the sonor and get the surface of the head wet and tighten it down some, let it set and then transfer it to the Ludwig?

Also, the head has two very small holes (~ .5 cm) that have been taped with masking tape. Was wondering if for that reason I'd be just as welll off to not even mess with it, or if it'll still be fairly durable.

Thanks!!
