Not all JDM rods are hard to source. The Tenryu Lunakia comes in 5'8" and 6'3" models, designed specifically for casting light jigs. The 5'8" model has a max lure rating of 2g (just over 1/16 oz) and a max line rating of 2.5 lb. Sounds like it was intended for your exact use. The 6'3" model has a max lure rating of 3g and a max line rating of 3 lb. Both have solid tips. Both are in the US and in stock.
