Hi Jim,
I agree with adg101. I believe the benefits of bi-wiring likely become greater when running speakers with large, power-hungry low frequency drivers. For your Wharfdales, I would simply run those HT Pro 11+ cables, or your GHs, full range to the MF/LF terminals, use some high quality jumpers to the HF and enjoy the music.
I would consider using jumpers made with something like this:

Since these are solid core wires, you can easily use a single wire without connectors as jumpers.
If you jump from the MF/LF posts to the HF posts, I would probably select the 16-18awg wire. If you jump from the HF posts to the MF/LF posts, then I would use the largest 12awg wire. Four 6-10 inch pieces should work just fine. They also offer the same OCC wire as stranded, which may be kinder to your HFs. You may need spades or banannas if you use the stranded wire.
