Gold Seals. They are expensive (less so now in Canada thanks to the exchange rate) - but, since switching to them 6 months ago from Aces and Ultima Lites:
Skater 1:
- double axel
- two triples
- Level 2 step sequences with +GOE
- spins that are fast, centred and +GOE
- better edges
- quiet skating
- clean landings
- higher PCS overall
- more height in jumps and more controlled takeoffs
Skater 2:
- axel
- several doubles
- quiet edges
- no more complaints from judges about "scratchy turns" or "noisy edges"
- faster, centred spins
- better PCS
And, weirdly enough, for both - less sharpenings ... even the Lites .. the Gold Seals hold an edge better.
