After messing around with the pistons a little bit, a couple things I've noticed:
Compared to the mod pistons, these ones will activate as long as there's powered redstone next to them, as opposed to only on the rising edge. This means that if you push a piston next to a block that's got a redstone current on it, it'll activate when it gets there. This is MUCH better than the mod version, where a piston would only activate when the current turns from off to on.
However, one HUGE change from the mod (at least, I
think that's how the mod worked)version that I'm absolutely hating (and hoping it's a bug) is that sticky pistons are only "sticky" when they're pulling back. This means that if you have three pistons chained end-to-end, they'll expand just fine, but they hit a problem when retracting, even if they retract in the right order:
First, the last piston pulls back, all's well.
Then, the middle piston pulls back, pulling the last piston with it. Again, everything's fine at this point...
Finally, the initial piston pulls the middle one back, but since the middle one's stickyness doesn't work, the last piston ends up staying where it was.
And a few pictures:
