Need help on decision to arb or not

[goblue12]

I have a 1000/333 on S. Zhang -300 in this tennis match.

Opened at +150/-169. Pinny currently has +488 / -625.

My book which I placed the original bet has the other girl (Z. Kucova) at +550 now, probably thanks to my action.

Both bets would be +EV on Pinny's price.

Do I arb or let it ride?

wow so u would be arbing a -300 and +488? thats a huge arb, i'd probably take it unless losing this bet won't hurt at all.

its usally the more +ev decision to just let the wager ride

No. I would have +550 and -300.

EDIT: It's +580 and -625 at BetFair (the market) so I'll probably just let it ride.
EDIT #2: Now +380 and -795 at my shop.
