I use the traveler all the time.
To expand a little what cruisingcat wrote, in wavy/choppy conditions its good to trim more twist into the main so I keep the traveler further to windward and loser mainsheet. This makes the main more forgiving as the boat move around in the waves. Contrary, in flat water
I move the car down to leeward a bit and crank the mainsheet harder with makes for better pointing. Flat&firm mainsail
for pointing, full&soft for drive and forgiveness.
My boat doesn't have a vang. As the wind
angle opens up, I sheet the main with a twist to my liking to the wind/wave conditions and use the traveler to set the main at the right angle. As the wind
changes in direction/strength I would mostly use the traveler. But if there a major strength change, sheet tension needs to be adjusted.
Light stuff its its the opposite. Leach tension is more critical.
But in all, once set I change the traveler more often than the mainsheet.
On the subject traveler vs. bridle
, every mainsail
setting can be achieved with both systems. But I do prefer the traveler because if I want to change the setting it will be either angle or leach tension and with the traveler its only one line, traveler or mainsheet. With the bridle
, both ends needs to be adjusted ie. two lines.
