i definitly think so, iv got a 2500 daiwa regal and 10pound braid, my biggest shad with a spoon was 2.5kg,i'm sure if i had2 hook bigger i could land it? the 4000 packs more then enough line 2 land most shad you will get along our coast...awesome little reel by the way!
i use the slade 2500 for elf and leervis so the 4000 will do the job 1000% but use 8lb or 10lb heavier than that and it will not feel so lekker (line to heavy for reel)
