Topband: Feeding a Base Insulated Tower

[Larry - K1UO]

I have a couple questions I have never been able to find any direct answer for...  so... out of curiosity...

1:  I have never found or read any information concerning the best way to feed a base insulated tower.  Is it better to just feed one leg from the matching network or would it be better to feed all three tower legs at the same time... OR... does it even make any difference at all?  Any out there that have tried both ways?

2:  Also..Now there is a static bleed choke across only one leg insulator of the vertical... Is it better with one on each leg across the base insulators?  (each leg is insulated with T10 Garolite solid rod type insulators about 18 in long and milled to fit the Rohn 25 tower legs..  4 in. insulated gap left between the upper tower and lower 2ft of tower left out of concrete base.)
