i just go by my results . my first 5/8 did a lot better than the 1/4 wgp at the old place . the two 5/8wgp's i made here weren't impressive here 6-7 ft off the ground IMO , but the sigma/vector style did better on the ground and is doing much better in the air a little . W8JI suggested my 1/4 wave was constructed wrong ...... maybe so . that seems odd though ...... it was just a simple open circuit starduster type wire contraption . maybe i did build a really simple antenna so wrong , and much more complicated (IMO) antennas much closer to perfect . or maybe it's because i didn't compare at similar tip heights ..... just similar feed-points . but putting a 1/4wgp at the same tip height as the S/V just is not a option for me here and i doubt even a absolutely perfect 1/4 wgp at the same feed-point as the S/V type would perform nearly as well .

so for my situation a 1/4wgp is not the most effective omni and i'm not gonna take a step or two backwards in my performance results just because one of the (apparently/supposedly) brightest antenna minds on the forums doesn't like or care for my current omni .

W8JI had this to say about antennas bleeding and splattering when i commenter on how the imax is known to bleed ......

"So you are saying an antenna can cause "bleeding and splattering"? Exactly what is the non-linear mechanism in the antenna that does that? I wonder where statements like that come from, because unless the antenna has non-linear components in it...it cannot possibly cause intermodulation."

to which i had no reply .......... and i don't know what a "non-linear component" is . but i know imax and antron antennas are known to be bleeders and doing as you suggested bob (isolating and adding a proper choke and ground elements) helps or cures the problem .

or maybe the problem is im just a CB'er ? ...... maybe getting a piece of paper on the wall from uncle charlie will instantly make me smarter and make a 1/4wgp just as effective as my .875wl antenna within my installation limitations .
