I have a G4 that I have exactly where I like it. But I like a very stiff predictable and precise sled. With that said any version of the G4 or G5 is very capable. T-Motion has just become the canned response. Have spent some time on a G5 and it's nasty for sure. But they still have room to improve. For example torsion springs, you have this advanced sled with cheap torsion springs that add a second element to suspension tuning. The front end needs to be in line also. For me the G5 would still need a bunch of changes for me to get it how I wanted it.
What do you gain with removing torsion springs? How are they outdated? Only thing I can figure out is to adjust rear shock preload more precisely, but to be honest most riders don´t understand anything about shocks or suspension anyway. None of my buddies riding Polaris have never touched the preload of their rear suspension. Its more about suspension geometry and shock calibration if the suspension works or not.
All the race sleds with latest tech and innovations still use torsion springs (except Lynx). Maybe internet experts should give a call to race departments to get rid of outdated torsion springs, if they are too stupid not to figure it out themselves.
Torsion springs are easy to adjust, use the multitool that comes with sled to set torsion springs for your own weight and riding style between #1 - #5. Quick&easy.
What I see is this common phrase rolling around internet, complaining about torsion springs but nobody has any actual points or facts what are the benefits and why its outdated.
I see lots of people complain about sag. Well if you dont like ride height of your sled, adjust your torsion springs to whatever harder position and your riding height should change to fit your needs.
Afterall its all about how it works in real life. In my opinion, ski-doo has nailed the combination of weight transfer, ski lift and climbing ability. Fun sleds to ride but still very capable. Very difficult combination to achieve.
