25 kg barra , now that is huge and I can only dream about it . Congratulation .
Assuming you are fishing from a boat , I would use #200 in Shimano round type baitcaster which can accomodate almost 200m of PE3 line and I wud choose a better quality reel with 5 kg max. drag which is smooth up to that max. rating .
If you are fishing from the bank of the lake / dam with 25 kg barra around , you may need a
bigger reel and perhaps a #300 or even #400 in Shimano range albeit the latter is a bit heavy for all day casting , in my opinion . The bigger reels have higher max. drag and possibly can accomodate 300m PE3 line .
Recently I got stripped by a barra when using my #100 Shimano reel with 100m line in the spool , the barras would be around 6-8 kg fish only so one can only imagine if it were a 25 kg barra !
I was fishing from the bank of a large impoundment pond .
