I'm getting an 18000 Stella next which will be used for Stickbaits on bigger beasts. The 4500 will be used for live baiting for Jew in the boat, casting lures for Jew off the rocks, beach casting for Tailor and Salmon and casting for Tuna and Mackerel in the boat. Not really expecting it to be a skull dragging reel.
The 10000 Stella was probably a better all round reel, hence why a bit more line on the 4500 would be nice. But what the 4500 won't catch, the 18000 should.
