I'm looking into getting a fretless 5 this summer, and I've narrowed my choices down to: -Conklin GT-5FL -Cort Curbow 5FL -Music Man Stingray 5 Fretless I may just splurge and get a fretless 'Ray, because I like Stingray 5s a lot, and I'm not quite as worried about a one-piece maple neck as I used to be. However, if I decide to be frugal, I will look long and hard at either of the other two basses. Playability is of the utmost concern to me, because electronics can always be changed to fix bad tone. Anyhow, what are the necks like on these 5-strings? I'm mainly concerned with thickness. I can't play "modern" necks; anything thinner than a Stingray 5 is really just too small for my hands.
