Any advice on purchasing a new Bass?

I am looking to purchace a new bass. I have been playing for 25 years. I am in my early 50's.. Looking for something high end That will last for the next 25 years. With so many choices out I am finding it hard to narrow it down. Probably going to go with 5 strings. I certainly need a neck that just won't move.. Active/ Passive electronics. Been looking at Sadowsly - Lull - Modulus- even Fodera.. I've got the Carvin you see in my Avatar.. But it is a 4 string. I know... I'm all over the map... I play alot of club dates and also do the occasional Theater gig as well as blues and Jazz gigs.. I need one instrument that will handle it all . Light weight is important. I've got a good amount of $$ set aside for this purchase.. What's your suggestion...

 

Hey Jeff.. I hear ya.. You know lately I have had a bad case of GAS. I've got about 6 basses. They are worth $500 - $2,500.. I want to move them all. Except for the SB. The Carvin is a great bass and I do feel I can develop a relationship with it. I want a fretless and a high end 5 string.. that's it.. But I would like instruments that will hold their value. We all know Carvin re-sale is not good.. That's too bad..
