MCDM, the current loops can be used for both as that is the reason for their current location. I would change the sewing method and or the material solely for a stiffer/ more open loop. The only reason I would put another set of loops at 3 & 9 o'clock is out of user feed back. I personally use a rc harness as my lb connection and even then I prefer 2 & 10 o'clock. It keeps the rope closer together to help with wrap on the tree and its much easier to look down and connect to, instead of moving your arm out and twisting to see 3 & 9 loops. Might be different for others, but for me this is what ive concluded. Stand with arms relaxed, then lift your hand to waist level, mine ends up at 2 & 10.
As for addressing the spin off of a sit-drag, that is not the case. Sit-drag was not even on the radar as a saddle when I went to work on this. The sit-drag craze however is what killed this project since I couldn't come close to that price point. This idea evolved from pics of other old saddles and testing. I looked at what was out there and modified to make it work how I wanted. My molle saddle really enlightened me on what makes a saddle work. That saddle was heavy and stiff, hence the search for something lighter and more playable.
I got to see a sit-drag for first time recently as I bought 2 off here. I was curious what the excitement was about. Not trying to be mean, but they suck for me. Everyone is different, but the sit-drag isn't for my shape/use even if it was made from the best material in the world.
