Biwiring Triwirable Speakers

I recently got a pair of Wharefedale Opus 1 speakers, which have tri-wiring capabilities. However, I am using 4 conductor speaker wire. Should I separate the tweeters and link the midranges and woofers together, or separate the woofers and link the midranges and tweeters together? Thanks in advance for any advice.

tweeter and midrange together. the sound will benefit more from having the woofer cable separate from the others.
