An old friend of mine had an EB-0 that he strung with those Precision Flats as well. I got a lot of opportunity to play it, and it was among my very favorite tones that I've ever had. I used them on my P Bass for a number of years as well. I'd highly recommend them.
Yes, they have good tone.
The issue with short-scale basses is tension v. tone. You can make an E-string to have the same or similar tension, or feel, as the rest of the set, but it may go thumpy because the E-string will be so thick in relation to the scale length and the rest of the set that it loses flexibility and goes thumpy.
Concededly, La Bella solves the issue by risking thump on their 104 short scale flatwound E string to retain consistent feel. GHS chooses the other solution, which is what V. C. Squier did for Fender in the early days, (the standard flats set once they became Fender's primary string supplier was @ 50-100) by making the E-string lesser diameter, compared to what the math might indicate, to retain flexibility, which translates to more consistency of tone.
I prefer the feel consistency, and always keep an extra E string handy in case it goes thump. (Just ask Jason @ Fretnation!)
So it depends on the player's preference for solution to the feel v. tone issue that is inherent on all short-scale basses, especially the E-string. If a player chooses the tonal option, as the GHS Precision Flats and others which have @ 95 E-string, then my recommendation is to raise the E string a little bit to give it more room to vibrate to avoid fret slap due to the lesser tension on that string (string excursion), and the little bit more downforce required to fret it at that point also brings the feel back a little bit compared to the ADG strings.
That's another thing I like about the relatively new GHS Balanced Pure Nickels. Jon and crew have researched core/wrap ratios and get really close to solving the issue on these strings.
This is nothing new. Italian harpsichord makers dealt with this issue 400 years ago as they were figuring out how to extend the range of harpsichords in the bass and keep everything consistent in tone without making the broadside of the harpsichord so long it wouldn't fit anywhere.
