There were two distinct generations of Kryptonics, yours sound like the first generation, which I bet are worth a fortune now in good condition! The second generation were the lime-green ones with rounder edges, you can see a set of 70mm on my Taperflex board back upthread somewhere. IIRC the hardness was similar between ranges; red soft, blue mid, green hard. I was more a downhill speed freak than having any discernible trick skills so I went with the largest greens as they really shifted!
PS With ACS 651 that sounds bang on for slalom. What deck style did you have?
Arghh. Now I really am annoyed they have gone AWOL! ( I really liked those wheels. My wife wrote a song once, which included the line "...skateboard wheels and handlebars" after I had showed her my treasure trove of stuff I was keeping for future projects)
I'd describe the deck style as "fish" shaped (a bit like your RMI pictured at the start of this thread). Flat on top. Rounded edges. The kick-tail was a slim wedge glued and screwed on, then sanded upwards on the underside to simulate the real thing. Maybe not the best slalom shape but it worked well for me. It was made from an old side-board (parents went mental) I "found" at the back of the garage. The plywood worked well and I thought it looked quite handsome with a dark polyurethane varnish and grip tape on top.
My first skateboard was a bit of wood with a friend's sister's "borrowed" roller-skate separated and nailed to the bottom. Bent-over nails were the fixture of choice for many projects.
