Dylan, definately go the 10000SW for that brief, you can always play around with spools for different line classes (8000, 12000, and SOM 16000).
As Brandon suggests, have a careful think about the retreive ratio which best suits you before you take the plunge. You can change the retrieve ratio to a certain degree by playing around with spool diameters! There is a big diference in the speed of retreive between an 8000 spool and a 12000/16000!
