One of these days, some pretty smart individual will take one of them there supposed HI-FLOW filters that neither flow or filter, put a dust sock on it and then test how well it flows.
I'd be mightily surprised if it flowed as good as a stock filter does.
For all you folks running dust socks, why don't you just take some chicken wire, bend up a cone and put the sock over it?
Why buy a fancy cone filter if you have to run something else to make it filter?
