 Bob,

I'm just too spastic to keep up with 6 cables running down the inside of the fuse.

Grin,

After fooling with them for a while, I pitched them in the trash can and went to the Dubro nylon antenna tubes. I found that it was mpossible...at least for me...to get them attached to a spar/ladder without binding. So, my vote is: I ABSOLUTELY won't use the flakey/flimsey teflon.
