>> Yes, Harken bullet blocks are excellent.  The 29mm ones have a SWL of 300 lb.  A swivel will minimize the chance of things getting twisted, but may not be necessary.

>>> #5 (5/32) is more than adequate.  It comes in white or black.  It's very durable and has lasted for years at my and K4EET's locations.
>>> It comes in various spool lengths and is inexpensive.  I usually buy 1000 feet, but I think it is sold in as small as 500 foot lengths.
>>> I've seen it on eBay too (I think it's Winne directly).
>>> I have enough if you want to get a length from me if I'm not too far from you (near the Ches Bay Bridge).
>>> 
>>> Be certain that the pulley width is properly sized for whatever line you use.  That way it won't be able to slip off between pulley and cheek.  I often use Harken or Ronstan small boat blocks, but inexpensive hardware store pulleys can work well too - just check the size.

>>> Thanks to so many good off-reflector comments, too! Sure appreciate the kind and thorough advice, as is this is my first foray with pulleys, ever. 
>>> 
>>> The pulleys will be holding and hoisting the ends of a 80/160 dipole with balun. The center of the dipole is pulled taught between the 2 towers.
>>> 
>>> I have Lowes 80lb synthetic rope- will that work if I double it at the tower Leg , or is there a better "easy and able  to obtain today" rope product recommended. I would need it in 120' length.
>>> 
>>> I have bought a bunch of various high quality harken pulleys of regular and large size. Some with swivel. Any other ideas welcome!
