That's a beautiful bass. May you play it for a long time and make great music.
Many professional-level players feel that the
DR Sunbeams are in their own class (they are nickel rounds with a round-core). They are truly a great string and are a kind of standard in my opinion. They really put out a slinky, juicy fretless growl. If you want a slam dunk great modern fretless sound, I would start there.
To cut to the chase: I realize you mentioned Egan and Pino, but if you are into the Jaco-derived tone, there is a very good chance that you will ONLY be satisfied with the Full Monty for fretless sound, and that means a poly/epoxy coated board with rounds. If you are a precocious player with a tone-fanatic mentality, don't listen to anyone who looks at you sideways when you tell them you want to have your board coated.
On the other hand, if you experiment with Thomastik Jazz Flats, La Bella Tapewounds, Grounds, etc, you might find that when you actually start to create some solid fretless tones
on the gig that something else beside the epoxy-thing will work just fine for you. You dig? Once you are actually laying it down; THAT is the true test for you and your tone search.
That being said, I have gotten some great tones from the La Bella tapewound series, but for a piezo-loaded bass there is definitely a "dead-zone" in the tonal spectrum (and a placky-ness) and after a while it gets on my nerves.
The Thomastik Flats are a
great string, but when I got my 35" scale Veillette Paris I couldn't get them to focus. They worked just fine on my 34" scale model, but for me, not with the higher-tension of an extended-scale bass
Waaayyyy too much is made of fingerboard wear for fretless. If you have a solid chunk of ebony, you are going to do just fine for a long time. You can get a good ebony board dressed for years on end if you need to.
