All Canadians in Canada are Canadian, Akz! I’m pretty sure I’m Canadian, too… and I’m an American! (At least I sometimes WISH I were Canadian anyway.)
If you wait for the power bar, a “high-middle” or max power push is best for initial velocity. Try to keep your “stone” centered in the lane on launch, but you can finesse it a bit (not really realistic, but - hey - it’s a video game) with some sweeping off to one side or the other.
And - if you blow by the target because your sweeping was TOO AMAZING… KEEP SWEEPING! You might rebound into the target zone after all!
