VERY true. You'll notice that people like TechT release products that when put into the marker, they do things like scratch the breach etc The GEO2.1 is a lovely marker - smooth and quiet. Nothing is going to improve it's efficiency other than bore matching your paint. It's just the way it is. It is already soft on paint. I don't think I ever had a broken ball when I had one - even in -11C!Best rule in paintball with regard to upgrades 'If it aint broke, don't waste money trying to fix it'
If your gun, particularly a PE gun is shooting ropes then beside general maintenance you don't need to do anything . I learnt this lesson the hard way in the past :-(
