upgrades i've done...drag, spool bearings, sv spool...rest is just bling
As for spool changes, the 103 spool is one of the best out there, really. Excels at lightweight presentations and pitching, so I'm surprised to hear you are having issues at 1/4oz - that is right in the 103's wheelhouse. I'd do the basic maintenance changes first them decide if you really need a different spool. Luckily the Steez uses 34mm spool which is the most popular and has the most options for upgrade .
In addition to Plat you can look at:DetroitBassN wrote:Aside from plat where’s good places to buy spools drags and bearings? Please give links. At the time of purchase I was told I wouldn’t get better spool bearings then what we’re on my JDM Steez 103HL. The drag I definitely would like tougher it’s getting worn. I took this reel apart only one time fully before to clean it. I was told to stick with the red Daiwa’s oil but don’t know what I should use for grease. I also don’t know where to buy that red Daiwa oil as it wasn’t for sale anywhere at the time. It handles lighter lures well just wish it could handle 1/4 oz a little better. Open to spool recommendations and places that carry them. Thanks
