OK, I purchased the Imax-2000 which is a 5/8 wave antenna. There are 2 options
for a ground plane kit:

1. First is a four fiberglass 6 foot radials, angled down (appears 45 degrees),

2. This is another kit. It has four aluminum 7 foot radials. This is horizontal,

Which one would be better?

Personally, I would use neither.

You should give Frank's suggestion a look as it does contain a lot of
information on antennas.

But to answer your question, your particular type of antenna, like the
A-99, is designed to decouple with no radials. Adding radials to this
type of antenna does very little to improve performance. It's more
about marketing hype than actual performance improvement.

I should have been clearer. I wasn't trying to improve performance, since it is
a 5/8. But from the reading I have done (no thanks to anything Frank posted), I
was simply seeing if thise would lower the angle of radiation, and reduce
potential for any king of interference. I am sorry id my lack of knowledge in
this field, insults Frank.

The Imax is actually longer than 5/8 wave. Like .64 wave.

How far off the ground? The lower it is the more effective the radials are
due to take off angle, the higher you get the less effective. I have heard
use them if the feed point is less than 36 feet. My Imax is less than that
and I have no radials. It performs VERY well. But new tower is being
contemplated!!!!

Damn..... BuryFlex, Imax, Sounds like we have a lot of the same stuff !!!!!!

Not to be a smart ass or anything, but if you convert .64 into its
fractional equivalent, what do you get?

According to this, they're damn close:
