I can only speak from owning a car with cut springs. as this was done before i bought the car.
it suck's ass. Every time i would turn the car, you could hear the springs making a popping sound. it was as if they where binding pretty bad.
when ever my car hit a bump i was worried the springs would fall out lol
The ride was freaking horrible.
Not to mention it was a nightmare getting on the interstate. every time i hit a bump it felt as if the back end would come off the ground.
I'm not saying you shouldn't do it, as maybe there is a specific way they need to be cut, and mine could have just had a crap job done.
I will say that, it ruined my thoughts on cut springs.
