Hybrid boards?

I've been noticing as I progress in riding I find that I got that old speed bug from when I was downhill skating. I've watched a few vids here and there with people riding shortboards and doing checks on toe and heel side and thought to myself "I wanna do that" but, Galveston surf doesn't really let that happen especially on a shortboard. so I looked into a fish but read that they can be restricted to mellow to a lil bit bigger waves and figured I'd do that till I saw a hybrid! the one I was a 7s slipstream and the sale pitch was nice and all but I wanted to know more about this paticular board. from what I gather on reviews that it's almost an all in one board built for speed in both small and big waves. I've been itching to ride soemthing fast on the tanker waves in the channel in Galveston and tear up those forever on going waves. Does anyone have any experience with these boards? I'm not looking to buy not with in the next 7 months or so till I know I can handle bigger waves so I'm trying to get ideas of what I should go for. I just want thst all in one board that can ride small and big waves but be quick and nimble.
