Miss kitten, let's have a deeper look on the weapons:
Garuda's Talons -
Wind Resistance+15
Accuracy+25
Critical Hit Attack Power+40
Chance to inflict wind damage

Sphairai -
MP+70
Evasion+30
Attack Power+60
Refresh+5
Increases Shoulder Tackle damage

It has slightly higher DPS that most probably makes up for the increased wind damage, looses on accuracy and crit power, but gains evasion, refresh and +MP to maintain fists and a good deal more of attack power.
Does that makes it more right? I wouldn't know i'm not a monk, but a straight DPS comparison is not a good idea.
