i do like 224 and 222...
but i definitely have to agree with everyone with 217! when im in a rush...i can use this brush to do my entire eye -- brow, crease, lid, outer third, blend!!
also..i have a lot of the other brushes --- 224, 222, 272, 239, 275..yada yada yada....and i just got the 252 and i seriously have no idea why i waited so long to get this brush. i personally think its amazing...it does an awesome job laying down paints or shadesticks..then i use it for my brow and lid colors...and in a rush, i can use it to help blend too! maaan... i<333 that brush!
