Ahhh...you didn't mention trackdays.
Naturally,you're going to give the clutch a bit of a workout at starts,and the number of gear changes under heavy load isn't going to be the same as on a road.
If you plan on a good number of trackdays,then I'd recommend the Spec Stg3+ which I have.
Feels pretty much like stock,and will handle a huge amount of load(570lbs) but it is an SMF setup,so you will get a bit of grumbling at idle,but you won't notice that on the move.
What I'd do is take what I've said,and talk to AMD as well about it,and see what the best compromise is.....as you know,they've done everything on my car,and you would be getting good advice.
I used a Sachs/LUK setup until I had the engine built with new internals,and we turned the boost on the old GT3071 up,and then the Sachs began to slip,hence the Spec clutch.
So yes,for road use,the Sachs is reliable,works well,and will not give up easily,but I think for track use,you may want something tougher.
