In reply to Chloe:
Hi Chloe,
I've always liked the Scarpa Instinct VS for sport climbing, as they offer a bit more support than the Maestros, which I personally found a little bit flat and floppy. They also benefit of having the same slightly firmer rubber, Vibram XS Edge.
When it comes to the VSR, which you also mention, I absolutely love them for bouldering, but due to them featuring Vibram's softer rubber compound (XS Grip) found that they creep a little on smaller edges whilst sport climbing. Not sure if this is the same issue you were having?
Other potential ideas include the Vapour Lace, although I haven't used that so can't provide a professional opinion; however, from what I've seen out at the trade shows it like it could fit the bill for you.
Hopefully that's of help
