The radius of a blade doesn't make as much of a difference as the spin rocker does... the gold seal has a smaller radius than the pattern 99 does... I've heard things both ways as far as which is better though, and ultimately I think it comes down to personal preference.
Gold Seal's are $395 from Kinzie's closet and $468 for the revolution version, if that helps make the decision easier
My understanding though is that the revolutions are still carbon steel, so you don't get any extra life from the blade for the extra cost, it's just the carbon fiber chassis that adds to the expense. 440 stainless steel Paramounts are also in the same price range at just $450 from KC (and there is a gold seal profile available in those, and the name/profile is actually licensed from Wilson, not simply copied), as well as the Matrix Supreme (their copy of the Gold Seal) at $385.
You could also consider the matrix legacy if you were otherwise happy with your current blades.. cheapest I've seen them is $199 from Sharper Edge Skates.
I don't know why anyone would have needed a special sharpening jig for the Ultima Lite? It's basically a traditional blade with cut outs. You can still get those form some retailers, if that's the blade you still want.
