Best metal bass strings

I am a bassist and as I've got a rather unique instrument I have to use the Dingwall strings that are made for it..but, I'm a big fan of the following brands: DR and GHS. I like tapered cores so I like the Hi Beam DR Long Necks and the GHS Contact Core super steels. I like Stainless Steel strings alot more than nickel, they're brighter and more "cutting", but they seem to die faster.
