Mid-sized baitcaster/conventionals are probably the best fit. Calcutta 400, Abu 6500 (many versions to choose from), Penn 965 in level wind models. The Newell 220 or the Penn 525 Mag would be a nice fit if you want a non-levelwind reel.
I have a Sabre 1088--virtually identical to the Rainshadow--and it sports a Calcutta 400 most of the time
