I believe the ones on the right are the HF-2? I think you wrote HF-42 by accident. I have the HF-2 on my car (20") for my winter set. I like them, but they are very similar to the GTS OEM spider wheels, so I would probably go for the the HF-4T
I never liked that flower pedal or snowflake look. You can create some neat looks with power costing. Like a silver base with a translucent black over it, even add a 3rd color to give it more depth and 3D look.
