I'm not sure who you are replying to here Dale ....
But anyhow - For me Daiwa make the best baitcast and spin reels atm ...... been buying Daiwas as opposed to Shimanos over the last 12 years - ( bought miss stella 4 years ago ..... and so underwhelmed by it)
The Zillions and Steez all suffered from poor drags and have been upgraded - no dramas .... best move possible.
As for Warranty .... I heard straight from Daiwas Shannon Watsons mouth that drag upgrades would void warranty - reels could be overstressed ....... a direct question posed to Shannon on an upgrade for a Steez 103.
