With similar drillings, the Violet is going to be about 10 boards stronger than the Slate. On a THS, the Slate would be something to play up the 5 board whereas the Violet, you may have to play closer to 3rd arrow. On any carry down or longer patterns, the Slate would be virtually useless with the urethane cover unless you really strap on it.
After looking at your profile, with that rev rate, you may be about an arrow different. I would say 5-7 boards different and I would say about 5-7 feet earlier as well.
