What's this about a double Twin Strikes anyway? In most occasions with all the dots and/or impulse drive you probably need to refresh Twin Strikes anyway but if there was an occasion where I didn't need to buff Twin Strikes, I would use True Strike. Twin Strike buff will still make Twin Strike a 140 potency attack vs a 150 potency True Strike. Cut it out for simplicity's sake but don't say it does more damage cause it clearly doesn't.
