3/8 kernmantle. We do have some throw bags of lighter “accessory cord”, I think 7 mm.
I’m not familiar with that brand. When I started out buying rope I bought some “dual braid” and it was bad stuff. I forget the brand, maybe Samson. But it got all kinky. If Mark vouches for that particular rope, it’s good. Personally I like Sterling SuperStatic. One decision is whether you like nylon or polyester rope. Some people will only use polyester (e.g. Sterling HTP) for static rope applications because it has lower elongation. Personally I find it too stiff and too abrasive and prefer nylon. If you look at the working load limit (WLL) which is typically 1/10 of the breaking strength, a 3/8 inch or 10 mm rope is fine unless you are hanging 12 foot dishes or something. I think the main reason to have a 1/2 inch rope is for rescue where it needs to hold the weight of two people. Or maybe for rappelling down a tower with a descender, which I think is also supposed to be done with a second rope for fall protection. But I have a garbage can with 900 feet of 1/2 inch rope and it’s prohibitively heavy. No tower climber is going to want to pull that up the tower as he climbs. You will have to start with a lighter rope and use a capstan to pull up the heavy rope. You don’t appreciate just how heavy a 1/2 inch rope is until you try using one. Mark mentions 5/8, I don’t like to even think about that. But yes, 3/8 inch is the sweet spot. I have now told you more than I know about ropes, so take with a grain of salt.

I would actually go lower diameter at 3/8” Unless you are pulling up the tower itself 5000’ is plenty strong and considerably lighter than the 1/2” or the 5/8”. The one you linked to is a good rope. I think we have the 3/8” as our main haul line. We have heavier 1/2" and 5/8” ropes for climbing ropes.
