I've never met an english bit with a curb that was ment for one rein. By using the lower rein alone you are turning it into more of a leverage bit.
Actually the kimberwicke IS a one rein bit, not a two rein bit. The proper use of it as described here: The Bit Gallery - Uxeter Kimberwick
That said, the idea is you use the upper slot for less leverage and the lower slot for more leverage. Overall the kimberwicke is more severe than the french link, but if your horse goes better in the kimberwicke, then keep her in it (however that is not a dressage-legal bit). Without pics/vids there's no way to judge if she is engaging properly or simply lowering her head/poll and false framing. If you/your trainer have sufficient dressage experience to know the difference and she is moving properly, then I see no need to change the bit for your OF work. However as a rule of thumb I always make sure I can flat in a dressage legal bit as even for jumpers I want a horse that is properly engaging and moving correctly whether on the flat or over fences.
That said - my jumper prefers his mullen pelham to any simple snaffle. He will flat in a french link when I need be it for dressage or just for riding (such as coming back to work with a broken pinkie when I couldn't use double reins), but he always likes the pelham better b/c the mullen mouth and the fact that I use 99% snaffle rein making it one of the most mild bits out there.
Good luck with your horse in finding a bit that works for the both of you!
