I know they can "hold" 150' of 5/16" cable, but how much are you guys really running on them? I want to run 3/8" and I'm wondering if 125' is about right? I'd rather be a little short in length but be able to make a wicked angled pull. One of the great things about an 8274 is there are no support rods so you can load up one side if needbe, but how much is too much? Thanks in advance.
