I skated on used Gold Seals (came with my boots) when I was pre-bronze.
They were good blades- I spun well in them, and they sometimes at first felt like they did the turns for me, it was just so easy compared to the previous blades. However, they were my step up from Mirages (cheap Ultima blade that comes already on the boots, sold seperately it costs about $50- compared to Gold Seal's almost $600, Coronation Ace's are about $200 here). When I stepped back down to the low level Paramounts (and now Ultima Matrix Legacy) I feel I skate exactly the same. So the Mirage is a very entry level blade, and that was holding me back, but once I got to a true freestyle blade, there was no need for a top of the line blade.
Even if you can afford it, at the level you say you are, I think the money would be better spent on lessons then blades, or cute baby stuff... I'd go with the Coronation Ace. (Although really, I highly recommend looking at the Ultima Matrix Legacy- I am in love with this blade. It has a harder steel then all the other blades I've used and the edge rip it gets is incredible, with no change in my technique...) Ultima might be harder to get outside the USA though.
