Alternatives:
1. Just use an empty barbell. It's 7 feet long and weighs 45lbs.
2. Fill an appropriate length piece of PVC pipe with cement or rocks or something and cap off the ends. Make sure you use glue or something so they don't come flying off. I imagine a 10 foot piece of 2" diameter PVC filled with sand would weigh more than 10lbs. Wait, I guarantee you it would weigh more than 10lbs. Maybe you could even use a smaller diameter pole.
The last idea is the best. You should do that and save yourself abou $110.
Good luck.
