I haven't had a chance to use it yet!
I've used the older model, my mates one and I was sold right away. The drag system was so smooth, completely different to my Stradic, so I had to get one. I've used smaller Stellas too, in my opinion I couldn't justify the extra $400.
It does have a new drag system called ATD, some sort of automatic drag system. Basically what it is, on normal reels, when you set say 1kg drag, its locked at 1kg right... not on the ATD... the ATD is like a progressive drag. So it lets some drag out and progressively reaches the 1KG drag over a short length. I'm still new to it and haven't used it yet, so I'm not sure of the benefits as of yet, but I'm guessing it causes less strain on the reel.
Will let you know how she goes =)
