I suggest a trip to New Mexico. If you are going to commission a bass then, you owe it to yourself to play some basses and talk to the maker. Trevor is an enthusiastic, skilled and well regarded maker. I have heard two of his basses, both sounded great. Great players helped. I have not seen or heard the Ceruti model, beyond passing at ISB and am also unaware of your musical interest, size, and experience. A trip to meet him and play some basses would ascertain which model is most suitable, and if you like his basses.
