It seems like even with the same springs the TS01s are a good bit stiffer (and are fine on the puller, as I mostly wanted them for looks anyway) ... I have the hard springs in them, since I only want a very minimal abount of give.
With the soft springs the TS02s are very soft (even at 2 x wheel). I don't bash the truck (or really even run it that hard), but if I did they'd likely be too soft the way I have them and bottom out on the harder landings ... but for how I'm driving it, I really like the way the truck drives with them. So maybe one hard and one soft spring per corner would give you a better balance.
As they say, your mileage may varry ... but for my purposes I like them ... and I think they would probably work fine for what you want. They look good and seem to be built decent ... though I think not suited to race Clods at all, since there's not a lot of adjustments you can make.
