I've used almost all of em going back to when I used the stuff Hunter Safety Systems sells (big bulky knots with noisy metal on them), DIY stuff, to two years ago using the lineman and tether sold by Tethrd (good stuff but too bulky for me) to last year buying the the 8mm Sterling Oplux Tactical Saddle Line with the sewn eye sold by Wild Edge Inc.
Far and away that has been the best I've used (for me) for its combination of low weight, low bulk (no knots and 8mm diameter), and strength. Liked it so much as a tether i bought another this year to use as a lineman's belt so those will be the only two ropes i bring in the woods with both EASILY stored in one saddle pouch.
On that note i highly recommend avoiding a ropeman if you dont have one. I used two of them for a couple years but was frustrated that i could never find a lot of info on how safe they were and then started finding incidents where ropes were damaged during short falls as it clamps down so tight it flattens the rope. I just never felt comfortable with the unknown (lack of weight ratings) when my life depended on it and the extra metal i was bringing into the woods as the one on my linemans belt would occasionally clank on a stick or something when i was setting up. I switched back to prusiks this year and bought two of the "Poor Man Ascenders" from Wild Edge when i bought the additional Sterling Oplux line from them. I was pleasantly surprised at how well they work to free the prusik using one hand when climbing a tree! Literally works just as well as the more expensive Ropemans and at only $4.99. I personally wont miss the Ropemans one bit, i realize there are a lot of fans of them here.
I use these carabiners, light weight and strong with a 24KN rating. Most of the biners that i bought from hunting related companies would squeak when i was screwing them in or out whereas these have always been silent even in sub zero weather. The squeak wasnt loud but I never liked it nonetheless

You could buy the whole set up from Wild Edge Inc (minus the Metolius Biners)
https://www.wildedgeinc.com/store/p74/KISS_Line_Kit.html#/ or just buy the components as you see fit and put your own system together. If you do buy your own Sterling Oplux you would likely have to tie your own knots though which will add bulk, these have a factory sewn eye so the bulk is basically the same as a spliced eye. The bulk may not bother you but i said that at first too, just a thought.
Honestly though, you will likely NEVER stop tinkering or tweaking your kit!
