I was gonna suggest Octant but I suppose Mogue's right. Leo Crossbow +1 is also decent and I just sold mine recently for 500k or so. Maybe if you want you can buy that.
If you're doing exp parties (since you said pulling), you should also consider bomb core (fire bomblet if you have the money) and darts. Of course at merit levels, thieves don't use acid bolts anymore because the time isn't worth the proc/land rate or even the time that it takes your attention away from the mob. But pre-75 I'd say it kinda depends on your party. If you're at a camp where bolts aren't landing/proccing at all, you may just be better off using a bomb core and pulling with darts. I highly highly recommend considering this if you haven't already.
Staurobow works if you want to upgrade your Xbow, but personally I am not a fan of low delay crossbows (even though I do believe they give better returns on bloody bolts iirc).
