Which Wakeskate is the most stable?

I'm new to wakeskating. I have a Hyperlite (not sure which model but the deck is flat with foam top and it retailed for $100). I really like wakeskating but I'm not as stable as wakeboarding. I'm 6' about 200lbs. I don't do any tricks, just enjoy riding and cutting back and fourth across the wake.

Which wakeskate would give me the most stable ride? I have no problem getting up, I just want to stay up and ride a little longer.

Thanks,
