Hi Sam,
A couple of rods which would the fit the bill for you include:
Zenaq Fokeeto Tuna FC76-4
7'6" casts 60-110g (best match) max cast 140g, PE 4-6. Weighs 405g
Faster taper than most popping rods, has the tip of a tuna rod and bottom end more like a GT stick.
Hots Gipang Tide Lez 78MH
7'8" casts up to 120g PE4-6. Weighs 315g
Parabolic action, reasonably stiff all the way through - great mid weight popping rod.
A couple of the Smith rods like the WRC 80P and Keyholu 77 may also work for you if you want a rod with more stopping power, but they are more ideally suited to PE6-8 and will also throw heavier lures too.
Regards
