Lightest Flats?

I've got a beloved but beat up old MIJ P/J with a shot truss rod. I get by with light half-rounds but even those are a bit too high on the neck for my lazy old hands, so today I'm going back to the Rotosound Funkmaster crazy lights, even though I'm not a round wound guy. What are the lightest flatwounds made? Thanks!
 
Lowest tension will be TI jazz flats

As has been said...TI Flats.

In terms of the actual tension (as in pulling weight), the La Bella Low Tension Flats (42-100, 134.9 lbs.) are lighter than the TI Jazz Flats (43-100, 140.2 lbs.), although the TIJF's are the more "flexible" of the two.

The OP is more concerned about the weight on the neck than the flexibility.

Good info!

I have a bass with the LaBella LTFs and I love those strings. Like playing melted butter!
 
TI flats, being 43 56 70 100, are not actually particularly light gauges (low tension).
The overall choice of flats gauges in pre-packaged sets seems narrower than for roundwounds.
What SLaPiNFuNK wrote: You can go far lower tension if you want, but that may require buying singles. Using typical gauge ADGC strings at EADG will work fine.

Labella LTF4a or Ti flat do help....

In tension chart , LTF4a are lower than Ti flat. But, in real life are opposite, LTF4a stiffer than Ti flat.

Hopehelp

+1 on this ... I recently made a direct comparison of TI JF344 vs. LaBella LTF-4A ... TI JF344 are more flexible, less smooth and more loaded with high-miss than the LaBellas .. the LTF-4A sound more traditional, are super smooth and sit between the TI and the Chromes in terms of inherent stiffness/flexibility ..

Weight on neck? Try to pull a string under axial tension sideways .. the higher the string’s tension the higher the force required for displacing it laterally of a given amount (this of course apply to a given string model/type; in reality the properties of the material and the way it fills up the string cross-section will also contribute to the end result when comparing two different strings).

Why certain strings are listed as characterised by low tension when tuned, whereas they often feel stiff when played, depends on the way the string has reacted to the tuning and neck relief control process as executed by the person working on the bass’ setup .. if a string feels stiff when played, this invariably means that it has taken up a higher tension than another more flexible string having the same or similar cross-sectional properties (the same core we may say) and made up of the same material (the modulus of elasticity of most of the commercially available steels is, however, almost the same; hence, when we talk about steel strings, the material should have the least impact on the mechanical behaviour of the system)

With all due respect to the above: they are all wrong. The best lowest tension flats, because they are consistent, won't turn your fingers black, even toned, and have greater longetivity:

La Bella Low Tension Flats. Period.
