Let's build a subwoofer interconnect

I need a high quality 3 meter single subwoofer interconnect for a nice music/HT system. My speakers cross over to the sub at 80 Hz. I haven't shopped interconnects for several years. There sure are a lot of choices. I've got my preferred RCAs narrowed down to Bullet copper or silver and WBT NextGen copper or silver. I need help narrowing down further to the best assembled sheilded wire/RCA combination. Some suppliers I'm looking at include Bolder and VH Audio. I've asked VH Audio for a price on a 3 m Pulsar with the WBT NextGen silver RCA. If you were having a custom subwoofer interconnect built what choices would you make? Let's say we keep the budget for this litte project under $300. Member input is much appreciated.
