There isnt anything in particular abt either reel that makes one significantly better than the other, Varos.
I've had the Biomaster 2500 for ages, a Stradic 2500 for abt 2 months, and both reels are value for money performers.
My Biomaster has accounted for a heap of jews and kings under heavy drag and the only thing I've replaced on the reel is the drag washer, which is now Carbontex instead of the standard material.
Basicly, if u can get a Biomaster cheaply, go for it.
