2005 Sierra Wiper blade contact with windshield
 

The problem is: on the passenger side the (original) windshield curves so much that the wiper blade does not make solid contact with the windshield. This leaves a portion of the windshield with rain or in freezing temps sleet or ice buildup which exacerbates the issue.
I have tried numerous aftermarket and "oem" wiper replacements for my 2005 GMC Sierra, from $3.00 blades to $25.00 blades.
I have recently also used a zip tie on the opposite end of the blade to apply more pressure on the non contact end resulting in a quickly worn out blade.
Where can I get blades that create a full contact with the windshield?
