I've never met any trader that uses only line charts. Everyone mainly uses candlesticks, but I know of a few guys that prefer bar charts.
If you seriously are considering to trade mainly off line charts you're setting yourself up for a huge disadvantage. A candlestick tells you a lot more about price action than a line does.
The only time I ever pull up a line chart is to check if the a stock or futures made a new high/low (by few ticks) before it reversed, because the tails are harder to see in tightly outlayed candlesticks.
Also, a fake print can greatly distort a line chart, whereas you can see a b.s tail on a candlestick.
Good luck
