My problem with the Jul isn't me not liking it, but my climbing partner's inability or unwillingness to use it...so I use a GriGri. I stopped using my Kong GiGi just because the new Reverso has been damn smooth with a metolius belay biner and it's more functional than a gigi. All good systems, just depends on preference and squabbling over an ounce of weight or less here and there. As for rappelling, I really don't like it. An autoblock not with a Sterling Hollow Block is foolproof, smooth, and having a prusik on you is always a bonus.
If my partners liked the Jul, I'd use it
