if you use a spheros.. change out the felt drag washers! they will heat up and melt if you dont.
SMOoOTH DRAG *** Can Stop Anything *** - Dawn will need the dimensions of the drag washers so she can match them up with some carbon fiber washers.
I would pony up the extra and get the Shimano Saragosa. they look like they are more comfortable. the handles on the spheros are too small for large tuna.
