Hi Tangles
I see 3 obvious choices for you:
1. Grinfromeartoear - to date this has produced the 2 best results for Panorama broodmares(Smiling Shard, Make me Smile) and you are breeding back to the same family
2. Village Jasper - to get a 3/4 sibling to Arber who is a very nice horse
3. A Cam fella line stallion - Panorama mares have crossed very well with Cam fella stallion. Depending on your budget, you could consider Aces n Sevens, Four Starzzz Shark or Bettors Delight
Hope this helps.
