Umm...you picked some very different skis there. For starters, the Jeffery 96 is 6mm wider at the waist (which is a fairly considerable amount). The Jeffery is going to have much more rocker and will feel softer in the tip and tail but stiffer underfoot. The TW Pro is a pure park ski, the early taper will give it a quicker turn radius. Neither will wash out on big jumps, that for sure. The TW pro will be a bit quicker to swing around on rails, the Jeffery will be a bit more stable at speed and will be much preferred in fresh snow. If you're looking for quick swaps on rails go TW pro, if your looking for a wider ski that will be fun if it snows but can also kill it in the park, go Jeffery.
