anyone familiar with holley commander 950?

I know all the proform carbs I have been around were good carbs,BUT know nothing about this new holley stuff.but everything I have read or talked to the people that has them thut they were the next best thing since sliced bread.If I were still racing and could afford it I damn sure would try it.and keep everything else just in case..I think that's how we accumulate so much stuff..haha..hope this is a help........Artie
