[TowerTalk] LMR600 up to the top of tower ?

[Robert Harmon]

I have a 380 foot coax run to the top section of my motorized tower when it is fully extended.

I am changing out all my old RG213 and thinking of saving a few db by going to LMR600 up to the top section then 
LMR400UF up from there for the rotor loop and up to the 40 meter beam and triband/warc beam on the mast.  
What do you think of LMR600 for this run from the shack up to the top section for a motorized tower ?
When I lower the tower I am thinking I could coil the LMR600 into maybe 5 foot diameter coils on the ground.
BTW the tower is 90 feet to the top of the top section when all the way up.
Is this a bad idea ?  (I am hoping to avoid the cost of the flex LMR600UF if I can.)
A side issue is I understand I have to be very careful not to nick the copper clad on the center conductor 
when installing a connector on the non flex LMR600.   I would use the Davis PL259 connectors for LMR600.   Anyway maybe this usage of the 
LMR600 is not a good idea, what do you think ?
