7/8ths and up is fine. I've found the 1/2" too easy to kink even by 
stepping on it.  What ever I lay our seems to get stepped on before 
burial, or I end up trying to make a large curve/loop with my hands at 
the end with the result being a kink in the middle. I gave away a couple 
lengths with connectors. I much prefer LMR600 compared to 1/2" Heliax. 
Of course I prefer 7/8ths Heliax to either except I never seem to be 
able to find it.

I learned the expensive way that the UF versions of the LMR series do 
not stand up well out in the weather. Naturally they were the 28' 
pigtails at the top of the tower after having purchased 600 feet of 
LMR-600UF  That's now in the conduit where it's protected<sigh>
