I have the pvptool paid version and I still use this out of convenience. Even though the paid tool can do the same thing it's just so easy to start this up, press play, and fish away. Got to 450 from below 400 before Cata release using it.
Also, as an aside, I've been using pvptool WITH relogging for six months or better. Never been hacked. Maybe Pirox did do something not quite on the up and up at one point, maybe he didn't, that's not for me to speculate. After all, it is a bot, it's not exactly on the up and up to begin with. My point is that I can only vouch for what I've seen myself and that's that he makes a quality product that hasn't done me wrong in the time I've used it. YMMV.
