Congrats on the new speaks Bunky. How bout some pictures???
It would be nice to have some jumpers to make experimenting easier. PNF doesn't list jumpers on their site, but I bet they could make some for you. Pure copper sheet makes a nice DIY jumper on the cheap.
http://basiccopper.com/Biwiring does have advantages. But hard to qualify when two different brand wires are used whether it would be better to just use one with jumpers. You have to try it to know for sure.
Once you get your jumpers, try the diagonal (series) hookup that ecramer showed us. Using a single speaker wire, connect red to positive tweeter and black to negative woofer. You will get 80% of the effect of biwiring. Swap the hookups so that the red goes to woofer to see if you like that better, a tweak though up by Carl, which helps tune it further.
