[TowerTalk] Lightening protection - HF-VHF-rotator

I would like to get some real world knowledge about the use of gas tube 
lightening protectors.  Some of the names out here are Polyphaser, Alpha 
Delta and DX engineering.  Some of the units are "multistrile" and some have 
replacable gasFET tubes.  I was suprised that some of the units are not 
weatherized as in the case of the Polyphaser unit flange mounted.

I hope to have a 6M Yagi mounted over a C3SS F 12 Yagi and a HamIV mounted 
on the rotor base.

I would like some feedback on your experiences with these protection 
devices.  I have four eight foot ground rods around the concrete pad ready 
to connect to a rotor base (very heavy duty constructed of gaklvanized 
steel.)  The coax runs are aproximately 130 feet from the shack on the 
second floor of the house.

Grounding all of the equipment together is another concern.

Thoughts, help and experience is needed.
