Hi Ben
Nope, it's too thin sadly, oh and too short too
Minimum legal size is 0,35mm thickness, and for oval shootinglines this is measured on the thinnest side, and as far as I remember , Rio's 25lb ends up at 0,32ish... 35lbs is legal though
Longest cast in competition, would be I think, Steve Rajeff's this year, that went 54,5 m's in a howling gale :
Cheers
