Shreditor 112s are sick, but soft. They can handle speed pretty well, BUT if you get backseat or too far forward, you will wash them out. Definitely my favorite "jibby fat ski" tho, it inspires so much confidence to try new tricks. Its an extremely good all mountain ski if you have good balance, just dial the speed back from "10" to about "7".
Line Mordecai is significantly stiffer, better for crud, but still a jib ski. This ski intrigues me, I will most likely go with it next year as a jib ski, now that shreditor 112s are discontinued.
Kartel 116 will be a good option too. I had the jeffrey 114 last year, and it was great, but not as jibby as the shreditors. they didnt make me want to try new tricks like the shreditors do. however they were much better for charging and ralling through crud, and had better float (all on3p float amazingly). this would be a great option if you already know how to jib well, and need to take it to the next level.
Bibbys are too dead/damp feeling to be a "jib ski", but they can definitely jib if you have strong legs. I have owned them (190cm) and I thought of them as more of a resort powder charger that can trick a bit easier than the rest of that category... The jeffrey 114 or kartel 116 is definitely a better all around ski than the bibby, however the bibby is an amazing pow ski on par with the billy goat, just a different feel.
The Billy Goats are surfy, smeary (smurfy?) and pivoty, but not a "jib ski". Its a powder specific profile, thats chargey and smurfy at the same time, and does a great job in all mountain conditions if you have strong legs. It is directional and heavy, and even though its one of my favorite skis ever, I would not recommend it in this situation. Maybe if you only jib in a directional fashion (IE, only shiftys, grabs, 360s, 720s, and dont ski switch ever), then it could work, but its still heavy. Like this bibby, its in the Resort Powder Charger category.
