I remember it well, bud; the Spicy Flamer was also amazing:
Incidentally, KFC's Rancher and Brazer ranges reminded me of it when they came out.
Used to love them. I probably only ever get a burger at kfc about 1% of the time and usually go a fillet burger which is miles ahead of any of chicken burgers mcdonalds have got. Never tried either of the ones you mentioned.
