Rob , the 400 has a fairly thick mainweb even on the non cold weather block , cutting it only takes out .062ish of material and it doesn't make it any thinner than a 440 mainweb .
440jim is running the 400 in his dart like this, he's going LOW 9's (hi 8's ??), and has been for some time.
If you really want cheap chinese junk that has to be fixed you can find a source like crank cheaper .
