Should League Settings determine this move?? WHIR

[Tom Emanski AllStars]

alright guys, aj burnett was dropped in my league (i know this isn't the draft/waiver forum, but this deals with league settings). i've never played in a roto league 6x5. i don't know whether to weight my team according to the scoring system or pickup a player that will benefit my team

i'm considering dropping j.loney for aj burnett
we have a max # of innings pitch @ 1250, and i've all my starters got 200 innings i would be 1 starter short

do i make the move? there are a # of quality hitters on the wire (only a 10 team league), so i'm thinking if i do drop loney and konerko starts struggling i can make another move and pick up a big stick

fyi who is on the WW now: (so you can see)
andruw jones
matt kemp
delmon young
todd helton
edwin encarncian
