I am thinking the same a K5GW.

Do you have any gain antennas for the WARC bands ?
I also have a 22 foot chrome moly mast extending from my tower.  I had the same 
thought 
when I took down a yagi in the stack.  I decided to install a F12, 12m and 17m 
dual band yagi for the warc 
bands instead.  Glad I did,  I've been working a lot of DX on the WARC bands. 
I wouldn’t be to hasty about cutting the mast shorter.  You most probably will 
be glad you did later 
on for another antenna.  Its a nice problem to have, hihi.
