I got some regular old sliders on my F4 right now. Made by Intuative(sp?) I think. I'm gonna start stunting the bike more. Is it worth it to drop $100 bucks for the freestyle extendeds? Will they protect the bike that much more?

Thanks

And one other thing, I'm assuming those sliders go right where the ones I got now do, correct? Or I could rock two sets, now that's gangsta, haha
