Both the fast and the slow weapon have a 20% chance of proccing WF.
For Windfury a slow two hander is the best, because weapon speed doesn't really matter since the extra two hits are 'instant' yet still factor in the 3.8 speed. That's why big slow weapons are great for 'free' instant attacks:they are big blows. Even if a fast 1hander and a slow two hander do the same damage over time, the slow one will be better for instants because the slow one does more damage on a hit per hit basis.
That's why you'd see all those Warriors with Arcanite Reapers and slow 3.8 weapons back in the day: Because Mortal Strike is instant, the slower the weapon, the better because you'd get all the damage without having to factor in attack delay.
Some people prefer a faster one hander, but keep in mind that the fast speed will result in smaller individual hits. And in PvP you don't want sustained DPS: you want big, fat burst crits which can kill people fast.
I however suggest going the Elemental route if you are planning on PvPing with a Shaman. Windfury is a roulette of sorts: one time you one shot someone with a triple crit Windfury procs, but the remainder 80% of the time you are just going to be standing there with no procs and hitting people by 200-300. And people will focus fire you and you'll die in seconds. It can get very frustrating.
Another problem with enhancement is the gear you need. You need tons of Strength and Agility gear, but it's hard to find mail that has both. And it's very easy to neglect Stamina and Intellect when hunting for Strength and Agility gear (and you'll have to fight hunters for it, and we know how greedy they can be

), and you end up with 3000HP and 3000 Mana at 60, which means you get two shotted by everyone and have barely enough mana for a couple of shocks.
Back when I was an enhancement shaman, I made a list of the best possible Enhancement gear and, while it would have been great, the amount of work required into getting all that would have been insane. It's just so not worth it.
For 1v1 PvP, Enhancement is okay, but Elemental is better for group PvP: most of the shaman gear is geared for elemental / resto shaman; you'll do more damage and you'll also have more mana for heals. And you have control over your damage, as opposed to relying on the Winfury roulette as I mentioned earlier.
As a Shaman your job in PvP Battlegrounds and the upcoming arenas is support: totems and heals, with shocks used for crowd control: ES for interrupts; FS for snares and Fire Shock to unstealth rogues. A shaman has some of the fastest heals in the game (Lesser Healing wave is 1.5 seconds) and you also have an instant heal with Nature's Swiftness. A shaman who doesn't heal in PvP might as well not exist.
If you just run around with a two hander trying to kill mages, you'll not only look ridiculous. You'll be useless for your team.
