Sorry, lately I have a double beast sling as my rigging point and a single ring redirect at the base. This has reduced my porti use quite a bit and a single groundie can hold 100-200 lbs I'm guessing np. I think earlier you said the tht at the top and a single ring redirect at the bottom can hold 500 lbs.Like...... how many ring redirects would be needed to equal a THT's friction? If that is your question, it's very complex with too many variables, such as entrance and exit angle of each ring.
but..... if I had to guess at an average number.... 4 to 5 different large (28x20) rings might equal the holding power of the THT, or 4 beast rings.
That's what I am asking. How much you can hold with each system. Are my numbers right?
