IceGal23, my recommendation would depend on how flattened out your Coronation Ace blades are, and how you feel about your spin rocker and jump takeoffs.
If your Coronation Aces are pretty flattened out due to being sharpened down and you don't want to make the adjustment to a really round, full spinning rocker, then I'd suggest the Pattern 99 profile, which has a more gradual rocker. This rocker shape also tends to give you more distance than height on edge jumps, since you reach the bottom pick sooner on takeoff. If you go into your edge jumps with lots of speed, this might feel better to you.
If you want a rocker that is rounder right behind the toepick--desirable for spinning and for getting more height on edge jump takeoffs--I'd recommend the Gold Seal profile.
Both the Pattern 99 and Gold Seal have an 8' rocker radius, while the Coronation Ace has a 7' rocker radius. The rocker radius only comes into play on the back 2/3 of the blade, since the front of the blade is going to vary based on its particular rocker profile. When you go from a 7' blade to an 8' blade, what you will notice is that the blade is flatter from the middle to the heel. That's desirable for added speed on the ice, as well as more stability on jump landings. It will, however, require that you adjust to where you put your weight on the blade when skating backward. You'll need to get used to putting your weight farther back (pulling back with your back shoulder and pressing the heel down). Having switched from 7' to 8', I'd never go back now.
