- Vigorous in the nursery and feathers readily.
- Grower friendly - branches readily and naturally with low branch angles requiring little training.
- Branches weep and come down readily with crop load
- It is both spur and tip bearing, cropping on one year wood
- Highly productive - current indications suggest that it is significantly more productive than Gala and likely more productive than Braeburn and Fuji.
- Not prone to biannual bearing, but will do so if overcropped.
- The tree form enables pruning to be fast and inexpensive
- Responsive to chemical thinners and easy to thin chemically
- Limited information suggests that the tree is more frost hardy than Fuji or Gala

- Very low susceptibility to European Canker and is more resistant than Jazz™ (Scifresh) or Envy™ (Scilate), being similar to Fuji and Cripps Pink.
- In the nursery, similar to Gala for fireblight susceptibility due to its high vigour - more resistant than Braeburn and similar to Fuji.
- In the orchards, fireblight has not been seen and is regarded as better than Cripps Pink or Gala for resistance.
