I don't believe your choice in a reel is as important and your choice in a rod when it comes to deepwater bottomfishing with heavy weights.
Imo, retrieve ratio isn't as important and the hight of the spool and the torque generated by a reel. Comparing a 320 to a 330 and their ratio's in offset by the size of the spool. But you are generating more torque with the larger spool via the crank with the larger reel, but the retrieve rate is basically the same between the two when fully spooled.
I'm gonna crank on a few (too many) with a Torium 30 this year with the 6.2:1 ratio. Basically it's a high speed, non-levelwind (which I prefer for large fish) version of the tekota 700 which I've got a lot of good feedback from.
