Probably best to stick with stock then. I ran an aftershock many years ago and while I didn't bash it nearly as hard as I would have now (brushless really opened my eyes to what you can do), I did run it a lot and rarely had issues with the shocks.
My biggest issues with it were the two speed (not applicable to electric) and snapping the chassis rails from hard flat landings. That got old pretty fast as it's a PITA to replace the rails every other weekend. I sorted out a fix for that too by making a plate to tie the front/center together.
I don't know what the current xle springs are, but the RC Raven dual rates were a nice upgrade over stock or the yellow springs. Kind of a happy medium between the softer black springs and stiff yellow ones that Losi offered at the time. They have a few colors, I just went with black:
