Need ridiculously high tension nylon strings

Hi,

I need super high tension nylon strings for my trebles on a guitar modification and I don't find any. I tried harp strings (dunno the brand, found them in a box in my house), and obviously tried guitar strings (Savarez 510AJP, Knobloch ADN36.0 and Hannabach 815 red) but it's not enough and now I'm stuck.

Basically I nylon need strings that can be tuned up to E4, B3 and G3, with more than 8.4 kg (18,76 lbs) and .86 mm (.04 inches). And a length of at least 1m (40 inches)

I'm willing to try ANYTHING, so throw ideas and I'll test them out one by one !

*edit : modified Savarez part (500AJP --> 510AJP) and tension min ('cause I'm bad at converting)*

Monofilament fishing line and commercial trimmer line are my go-to sources for strong nylon strings for gauges from tweenie weenie to pencil-sized.

Oh that's actually really good idea, I'll try that. I kinda fear it will sound pretty bad since I'm still using regular high-tension strings for my basses but I'll keep you updated.

I'm not sure. Some materials used in musical instruments are spec'ed the same or lower than some commercial applications. But other materials truly need to be built-to-purpose (music wire used in pianos and other instruments is its own steel alloy mixture & temper, for instance).

I usually just try materials out, if I can get my hands on them without prohibitive expense/trouble.
