hmmm i´m no bass luthier master or similar...
but my teachers bass (200-300 year old bass from vienna) is one big crack...i don´t know if you can count the cracks the bass has (or even see them cause of the dark varnish

) but it sounds and plays like hell...
so you see cracks and else has nothing to do with sound and playability...
but i think a good look from a good luthier (hehe saw a previous post where daniel bradleys work was mentioned in the us of a, so maybe you can make a short travel here to vienna for a good luthier like him

) can help you in this decission....
