The two reels fill the same spot in the two manufacturers line-up but have some distinct differences. The toriums generate 15-20lbs(maybe) out of the box and have good freespool but it can use some tuning. The saltist will generate 22+ lbs of drag out of the box and have beautifully tuned bearings that will freespool longer than you need. A torium can be tuned to the same level of performance but will need a new drag stack including drag plate and for the bearings to be throroughly degreased to increase freespool. As far as the 4.9 vs. 6.4 it comes down to personal preference. Either one will work a jig or popper with the faster retrieve being better for jigging.
