i would use carbuncle, doomtrain and "reserved" hehehe the reserved summon depends what type of monster i'll encounter if its elemental or physical type.

true i loved it when squall was solo and i could equip every GF to him he was godlike then lol

Eden for the strength in attack power, Leviathon was a beast in the game when I used him, and lastly Bahamut. Best Summon possible.

I always like to use Diablos, Ifrit and Cerbrus, the demonic trio.

diablos cause he was my fav gf on my fav VIII charater..........................

I have to go for Eden, Bahamut and Leviathan. Recover may be cheap, but it saved me time after time on Ultimecia (thank you, Irvine). And, with all the time it took to get Eden, I'm going to use it as much as possible.

Buhamut (because i am a massive fan of him/her/it) Diablos (TOTALUBERPWNAGEMAN!!! hes lvl 99 for me so he hits for 99% of the opponents hp, for those that didnt know how his dmg is calculated) and the last one would bo hard to choose, its between doomtrain and cerberus, id probly go with doomtrain cuz he has my stat atk link, and i link 100 deaths to that making my normal attack have a 100% chance of inflicting death
plus with my 100 ultamas, full-lifes, shells, and somthin else that i always forget, it gives me a grand 80% to all elements (yes the green kind, meaning it heals me )

umm.. maybe i'll change my summon's,,

i'll level my Eden, Bahamuth and carbuncle to 99
