I would stay stock, myself. I don't think there are significant gains going aftermarket, and the stock reeds hold up well. Personally, I think V-Force reeds are hot garbage, but thats just my opinion. If you were going to do aftermarket, I have always had better luck with Boyesen.
On a side note, the stock reeds are the only ones holding up with a turbo. I think there are a couple turbo manufacturers making specialized reeds to go with their kits, but have no experience with them. My pro, destroyed a couple sets of aftermarket petals in only a few hundred miles, with a turbo. I ran a set of stockers for around 1500 under boost, and they still look ok.
