can anyone point me in the direction for some plants that will grow well [and hold up well] in fast moving water? the water flow i have in my tank isn't absurdly quick, but i have enough flow to keep water constantly turning. some of my current plants do bend a little because of the flow.

You have what we all need - good water circulation in the tank. Most, if not all plants will do well in that environment. The water flow will enable them to always have a good supply of CO2 and other nutrients.

In a lot of rivers the plants will bend in the direction of the water flow. When you stand in front of them and block the flow, you'll find they spring back pretty quickly to an upright position. :) Don't get too worried about the plants growing abnormally because of the flow.

You can always opt for placing the outflow of your filter facing another direction to increase aesthetics.

Some of the plants I find in rivers and streams are not what you might expect.
Few really fast streams have plants, maybe moss will be about it.

1-3 mph is about the limits.

Vals, Myriophyllum, swords, Crypts, Crow's foot, Waterworts, most floating plants, Crinums, Ferns, Anubias, these all come from rivers.

They will grow in our tanks with or without strong current, but I think if you sit down and really consider the aquarium, as eluded to by others here, high current is good for fish.

Why?

The plant beds really reduce flow rates.
So fish have a place to get away if they wish, but in the higher flows areas, they can get a decent work out and this acts like a much larger tank where they can really swim around in.

They get more exercise and eat much better, grow better, are more healthy.
Plants tend to stay cleaner, less settles on them, more compact growth forms.

I have Rotala wallichii right in very high flow, does great, grows about 1" per day under high light, I have to prune it aggressively weekly.
