Well I am prob quite close to your exact weight. I climb on xstatic and like it quite well. I use the akimbo often and find it superb I set it to creep just a bit to ensure no shock loading. The uni works great as well but for our size requires a drum for sure if not a lengthy decent equals in major wear. I also do a ton of crane work with the ZZ and have zero issues with that as well. For your tie in point friction savers I recommend using a rigging ring for that as it helps the wear on your device a ton. I hope this helps please reach out if you need any more advice.
