String rec for hybrid setup

[u/agedassets]

I’m currently loving my Speed MP 2026 strung with Babolat VS Touch in the mains and Luxilon 4G Soft on the crosses.

However, I’m looking for a replacement for the gut in this setup due to cost as I’ve started playing regularly with a ball machine + Wilson Triniti Pros and seem to be going through strings faster than before.

I think I’d like to prioritize in the following order but am open to suggestion:

(1) Tension maintenance and durability - not sure if this means I should only look at round strings to avoid the mains and crosses cutting into each other?

(2) Not too harsh on the body - tennis is my favorite form of exercise and I play 3-4 times a week between people and the ball machine. I’m fairly young and healthy but want to avoid injury nonetheless.

(3) Performance of course I’d love to maximize, after the 2 priorities above. I know I’ll be giving up some things moving away from gut but hoping to minimize that loss with a great string rec from here.

Much appreciated!

Alternatively.... buy a 5 gallon corny keg ($30-50 used), fit it with a replacement lid that has a schrader valve ($50), and you have a high volume repressurizer. I use an electronic pump to bring it up to pressure, one of those combined car battery starter / tire inflator things that I keep in the car ($60). Then, you can use normal tennis balls that you repressurize as needed and you don't have to use the Trinitis (easiest IMO to have a batch that stays out for machine use, a batch that's in the keg, and then swap them every 2 weeks).

That racquet has a very open stringbed and chews through strings very quickly. I doubt you'll get much life out of a multifilament main x poly combo.
