Not that I have tried the garcia reels, but for #2 and 3 spinners, I would stick to spinning gear.

While it is possible to cast these light spinners with casting gear, spinner is better suited, I think. If you decide to toss such light tackle with casting, I would drop down in stiffness and line diameter. 8# is going to be more appropriate.

The backlash in this case is caused by the lure slowing down abruptly in the cast, probably due to excessive friction dragging the line through the guides. In the 20 or so years I have been using casting equipment, spinning is far better for lighter gear.
