Use one in my Club Glove Burstproof 2, yet to have damage to my clubs. The airlines will always figure out some devious way to destroy your clubs, but this has worked well for me.
I used a broom handle for a long time, but eventually grabbed a stiff arm. I also take the heads off my driver, hibred and three wood and take them in my carry on for some added protection.
Go to the hardware store and buy a wooden dowel rod for $2 to $4 and have it cut to whatever length you need for your travel bag. Get 1/2" or bigger. Wrap a towel on the end of the dowel if its too short.
with almost 90% positive answers on this question most of us believe this is a no-brainer...
maybe i´m overly cautious but I like to put the stiff arm in the bag then wrap a towel around the heads, then to top i all of a plastic bucket goes on top. Has worked great so far.
