There is absolutely nothing wrong with wearing bell-bottoms while swimming laps in your marked lanes.

Seriously, it is your pool, and your not in jr. high anymore. Who cares what is cool, do what you want.
Sounds like you want the lanes marked so go for it.

Wear those bell bottoms and put in your lanes if you like them.

I dont see many of my customers using trim tile on steps and benches anymore (more specifically in Pebbletec pools). Mainly because the clarity of the water is so good, there is no mistaking where the steps and benches are. Back in the day, trim tile was helpful in marking the step edge for visual purposes. So unless there are elderly or very young children using the pool, we dont put in trim tile by default (unless of course its requested)

Swim lanes are different, if you are a serious lap swimmer, then by all means, put in a lane.

But like texasdad says, Its YOUR pool, do whatever you like best.

I on the fence right now making the same decision.
My PB is going to give me some excess tile that he has (that I like) but I'm still waiting for the labor quote. Perhaps that will make the decision for me.
I've only got a 40' swim lane that is diagonal across an L-shaped pool, and I'm worried about getting lost.
DH is thinking along the lines of spot step and bench markers instead of strips, so that would mean 3x3 or 4x4 glass tiles arranged in squares maybe 6" apart. gotta think that through still. (The glass tiles are about 3/4" squares - individually, you wouldn't be able to see them)

I like the example ithe link you posted, but it's a lot bolder than I'd like with lots of steps and benches.
