It has stronger turn over and a more complex taper than the Ambush as well as a textured head and AST.
While it has the muscle to turn over bigger tips and flies, it also can be very delicate, it is an extremely good fishing line, a lot of emphasis was put on how the line fished, not just how it casts... It has a thinner diameter towards the front allowing sink tips to dig in more and do what they are intended to do, versus a rope chain skagit head that is thick all the way to the front and basically acts as a bobber. However, because of the very dynamic taper, it still offers great turn over even with the thinner front taper...
It also is to me, an ideal length, some of these switch lines have insane short heads and it really hurts their stability in the air while not making much difference in how much room is required for back cast, a LOT of different lengths were tested and what was settled on would be ideal under most circumstances. You can still cast it just fine with your back against a wall and since it has an integrated running line, you can suck it in tighter when needed...
I cannot forsee anyone not loving this line.
An added bonus to the head being textured, if you use this line at night for example mousing with a switch rod "which it is stellar for", you know when you have stripped back into the head as you can hear the zip sound coming through the guides...
About all it has in common with the Ambush is it is a bullet taper...
