Looking to get into some lighter wheels. I hate to go from 19's to 18's but 18's are so much lighter. So my question is, what wheels should I look into? Also does anyone know the weight of these wheels, I couldn't find it. I will go a 9 or 9.5 and a 10 or 10.5 setup.

These

or
These = more expensive, and forged so probably lighter.
