2007 wiper arm tension

[Pinchlite]

I find the wiper arm on the drivers side does a lousy job of making good contact.Would this be due to a worn out spring on the arm.Also what is the best wiper blade for the yaris(cost is not a problem)Thanks for any tips/advice

I've used the Toyota sightline blades for years. I love them.
