hmm, if your wife is small built and no serious angler, maybe you should forget about a standard poppin outfit altogether.
even a (light by current standard) pe6 outfit capable of casting 100g GT bull is not easily handled by novice.
perhaps jus a stronger, longer spinning rod loaded w pe4 line, casting 40-60 g poppers/spoons will suffice. such outfit should also be able to jig up to 150g.
anyway, the average GTs/redbass there are not really big (mostly less than 20lb), and are more fun on lite tackle.
