Wiper Blades or Inserts?

Starting with my 2015, which I had until earlier this year, I replace just the inserts. I had the original wipers the whole while and saw no reason to replace them. I'm going to do the same for my 2023, whose original inserts are still doing fine. Have you tried cleaning the inserts to see if the lines will go away? I live in the Pacific NW where it does rain a lot.

 

IMHO; you should stick with the inserts. Once you replace the blades, you'll have to always replace the blades - since you won't know if they will accommodate inserts and type of insert blades. Unless you keep the original blades and don't damage them when you replace them.
I went with commercial silicone inserts several years ago. They've outlasted my original OEMs by 2x now. The original OEMs separated at the pivot point.

 

I prefer the inserts - easy to do, generates way less waste. Never had to replace the complete blade holder on any car I've had with inserts since 2008.

 

I just measured the driver's side wiper on my '26: 27"!
Largest one in my years of car ownership.

 

On my gen3 v I replace the inserts over 345k miles. Around 300k I replaced the blades with oem primarily due to faded paint. The oem blades are aero while aftermarkets are not.

I did replace the driver's wiper arm once due to stripped splines probably due to prior removals and reassembly.
