the hardside bags, like Cabela's (which is a fine bag by the way) is already over 20 lbs by itself...so if you have a 50 or 60 lb limit before you hit overcharges, how are you going to get all the gear you need when you can only have 25-30 lbs after the case itself?
If you have a takedown bow, get a great bow case, like the one seen on here called Safari Tuff by Str8Shtr I think, to put your bow in..and put that in a soft duffle to keep the weight down, with your clothes all around it. Your arrows are most important.
Get a good compact arrow case or build one out of light schedule PVC to hold your shafts, with end caps and you should be good to go.
I just flew to Saskatchewan and back and let me tell you, everyone is really checking the weights on baggage now, and you are paying through the nose for overages.
I asked about carrying a bow in carry-on luggage and was told NO WAY by two airlines.
