To me, the technique is the same, it just feels different and you need to get used to it; especially the teetering sensation you'll feel on top.
You do want to be "on top" although like you said, if your weight is too far back you'll ride out on the deck. Concentrating on your front truck being on coping helps that.
The other big difference is that you want to get off while you still have momentum to do so. Again, it's not so different than on a mini but it is different.
FWIW, my back truck is usually locked in heelside while my front is on toeside - although sometimes it's not.
