I have heard that also,but didn't get a commitment from Duke on "when"......
I f they continue to upgrade their traps in the manner of the past,I am sure the trap will be a great affordable trap.(with crappy chain,LOL!)
Since I know of few people with the hand strentgh to set fives,I am sure Duke will have a setter,or you could use one of the commercially available ones now on the market.Personally,I don't recommend the one you step on,unless you are trapping on hard-pan.
As for the 11's,I can no longer use any longspring trap(used them for 30 yrs)but if I remember correctly,all I did for tuning was,bend the jaw dogs up,de-wobble the pan,square the pan notch and dog end,and then bend the dog slightly up or down depemding on your set(down in water,up in dirt so you have commitment before snap.)
