GDS 6 vs. 7 blade upgrade for HX35W
 

Just curious if anyone has had any experience with the GDS 7 blade upgrade for the HX35W? I was wondering if the 7 blade was just more quiet or just a more modern wheel design? It apparently is a superback wheel like the 6 blade. Wondering if it may be an HE351 wheel?

I had a HTT 6 blade H1C years ago... it ran good and whined like a big dog in the cab. But, this will be going on my 93 W350 with more of a tow tune. I'll be the towing my 27' lowboy with the 92 sled puller on the deck, may have many hours on the road next year going to events. I'm just wondering about noise on long pulls over the road with the 6 blade but I want to make some good "clean" power as well.

Things have come a long way since 06, so my tune has alot different options then we had back then.
