Which SS is a better option the rest of the way out?

i have jose reyes as my starter and yunel escobar on the bench. i have been keeping my eye on mike aviles from kc. i am considering dropping escobar for aviles. escobar started off great but his injury history and numbers over the last month or so make me think that aviles may be a better option. aviles has been absolutely on fire. does anyone have any input? thanks
