Well Lil'Jeshua I'm going to make some wild guesses here.

The Fireup itself is physically 1' foot shorter than what it replaces. The 5/8 wave idea is about 5' feet longer than a 1/2 wave radiator...assuming the wire diameters are about the same. So just guessing I would say the Fireup will need approximately 11' feet of wire wound on the fiberglass rod to resonate as a 5/8 wave.

Again just guessing I think I see a total wire length that is maybe about 6'-7' feet at best. That may have some effect of increasing the current distribution across a smaller overall length and that could add a little current up higher on the radiator, but IMO it won't be much.

I would really be surprised if the Fireup tip, by itself, would resonate at a frequency much different than the stock tip of the A99 by itself. If you has a power source or an analyzer that is able to reach frequencies above 37-38 mhz you could probably check the resonance for your self...if you had an acceptable ground plane to mount the radiators on.
