Good news and bad news.
Good news? You have a lot of choices. Bad news There's a LOT of choices.
You are talking the talk of the uninformed, that's ok, we're all born ignorant, it's not a sin. So, let's help you get some real definition on what you really want.
Bay/flats boats are built to their environment, so you see a total different hull depending on what part of the coast you fish, From the north in Pt. Arthur, you see kenners, skeeters and champions, because the water is deep and rough. Get to Matagorda and they start to change to less deep/rough to shallow tunnels, down to Port Isabel and you need all the shallow ability you can get. So what's "shallow"? To a lot of people it's 18", to me it's 2" so where are you going to use this sled?
What makes it run shallow will also make it run hard in choppy water, your first compromise.
HOW do you fish? Stake it out and wade? Pole? Drift flats? Anchor and drown meat?
How many people do you really need to take with you?
Advice: Figure out what you're really going to do in it 75% of the time and buy what works best for THAT, and let everything else compromise, if you think you can get something for everything you'll end up with something that does nothing well. That's a fact.
