Getting 'em in the Lake

What would be a good technique to catch Steelies/Browns in the lake at the mouths while fly fishing?  I'm probably gonna go out in my float tube tomorrow, weather depending.  I'm thinking a short sink-tip, short leader, and streamers.  Sound good?  I'd appreciate any advice from anyone who fly fishes for them in the lake.  Thanks.

No real need for a sink tip. You're talking less than 8ft. of water, and no-litte current.

streamers I'd say. Very effective personally.

I have no experience fishing from a float tube, only from shore. Mostly I fish off the beach during the evenings and then only if we have a southernly wind or dead calm conditions.
 
I catch just as many fish off shore with a floating line and weighted streamers as i do with sink tips. If it sees it, the fish will come up to eat it if it wants to. You only need to get it down a couple of feet. I do an use intermeriate 15ft tip if I'm fishing unweighted streamers tied with boyant material. (bucktail) 
I can see advantages of a weighted line if you're fishing from a float tube in deeper water. Getting it down quickly. In fact, if casting towards Canada, a running line with a 30' head would be a way to cover a lot of water. But from My experience, the players will take it up in the column.
If you do use a sink tip, get one with a density compensated tip. It will keep the rig in a straighter line instead of a bow or shallow U shape.
