The only way to decide which way is best, is to get the quote from UPS for next day air service and go from there.
Based on this UPS page you'll get hit with dimensional weight cost going Air:
Which at 49"x25"x4" = 36 lbs / 17 kg
Ran it through the estimate rate site telling it from me (Minneapolis) to Winnipeg telling it I would pay at a UPS store and it came out to 268.70 USD for Worldwide Saver Shipping. Standard which does not get hit by dimensional weight is 26.46 USD.
