I looked up Vantage on the web. My modified Prince O3 Red is almost exactly the same as your prebuilt Vantage. Mine is balanced at 310mm, yours is at 305. My O3 Red is 334g. Your racquet is 330g according to the website.
I just bought the O3 Red a week ago, and I feel it has a huge amount of potential. Maybe there will be a truly good racquet, modified from a production racquet. The Gold O3 Tour is also great. It feels like last year's orange and black Dunlop 300G, only better.
Sorry if this has gotten off subject, but I think there is hope. There is going to be a backlash to modern super light, head heavy racquets that pros won't use, and most players don't like as much as their old racquets.
