ahm maybe i should have been more specific:
1. as a sword i have Revolver, if somebody would have told me where to find some pulse ammo i would have jumped directly to Lionheart.
2. my most powerful GF's are Shiva and Ifrit (lvl 50+) and boosted they inflict 1000+ - 2000+ dmg to Adel and 3000+ to Rinoa.
3. Squall hase the Highest strength and his limit attacks are renzokuken and rough divide (a total of 5200+ dmg if PERFECT) so i don't hurt Rinoa.
4. Qusitis has the biggest HP so i use her for healing.
5. Zell has Ifrit which in my case is more powerful than Shiva.
6. Shell truly does reduce the dmg of GF magic by almost a half.
7. As powerful magic I have Ultima, Flare and Holy but Holy heals adel, i don't know about the rest, haven't tried.
8. It's useless to use Zell and Quistis for phisycal attacks because at them i junctioned into health and elementary defense.
9. I don't have Hestaga
and 10. Aura might be useful in triple but for that i need cereberus and since his health is kinda low he keeps dying on me after Adel's Meteor and Smashing Blow (so it's a lucky shot to actually cast cerberus).

In the end while you solve the "problem" I have a question, which blue magic is the most powerful one at Quistis (death magic excluded)?
