Input on dual valvesprings
My reading comprehension is fine as I went to school and college when they still actually taught and spoke proper English, but someone's logic sucks.
FWIW, I don't use the Patriot springs, but I haven't heard or read a single bad remark about them.
Keyboards make instant superheros out of people...

BTW... All the "gold" this and that means nothing but the coating used. The metalurgy and heat treat are the key to a successful spring. Time and testing are the only true record of what worked and what didn't.
If some company claims they've never had a spring failure with the product they distribute, they are either lying or haven't seen the real world yet. Valve springs are perishables, just like spark plugs, oil filters and racing tires. All part of a good maintenance schedule.
You want springs to last forever? Don't drive the car.
