Quality, quality quality, , , it describes what you can expect from Shimano Japan market reels, and what Shimano Japan cares of the most. Craftsmanship lives more in Shimano Japan reels, and that is the reason serious anglers always seek after Japan Domestic Models JDM. Many of Shimanos are made outside Japan, and only $400 or over expensive models are Made in Japan.
Now many Shimano reels are specialized in bait finesse system tactics (BFS) with ultra-light rigs. Among them, I recommend 15 Aldebaran (US Shimano Core MG) which is great to cast 5-10gram 3/16-3/8oz rigs first, when you start finesse tactics. You may spool enough line capacity with this model. Other BFS models are the next steps to go further, and you may go deep to cast from 2.0g 1/16oz with bait casters.
