Short stroked gearbox on a 7.4 vs normal gearbox on an 11.1 Which puts less stress on the system?

Hello,

I just picked up a used https://www.patrolbase.co.uk/specna-arms-daniel-defense-mk18-sa-e19-edge
which is going to be my backup gun, but i want to make it all it can be. 

Tried it on 7.4 and it's fine, tried it on 11.1 and it's how I would want it. That said, the system recommends a 7.4.
The box is going to be opened and serviced anyway and my goto would be to short stroke the box and add a stronger spring to bring it up to around 350 on 0.2s, making it snappier and with a faster ROF. 

My question is. All things being equal is a short stroked box with a stronger spring (going to assume an m110 or maybe m120) and a 7.4 a better option than untouched gears, a slightly stronger ( M100 ) and an 11.1. 

Over to you

Cheers

y'know now you've made me think about it i'm not sure that's such a simple question to answer, at least in the intermediate case you're describing where either config is valid (ie you're not driving it fast enough where short stroking is necessary to avoid pme and there's enough volume overhead for that not to be an issue). there's arguments to be made both directions.

normally for me at least the stroke tends to be dictated by the barrel length (dictated by however long the gun is) and volume requirements, but then i tend to lean towards higher ratio gears and torquey motors with a boatload of precocking for snappy semiauto and not really giving a stuff about rate of fire unless it's stupidly low (ie i'm happy with 15-20 rps).

I think whatever you do will cause some sort of stress on the gearbox, just depends how far you want to go with it.
