My personal feeling, though, is that two sabres are better. The reasons: 1)rather have less of an attack penalty (because I hate to miss), [/QUOTE]
If you want the lowest attack penalty (ie the old school "To Hit" penalty) then 1 sabre is clearly the best because with duelling maxed out you get +1 to attack and +2 to damage (I think those are the right numbers)
With 2 sabres you get 0/-2 unless the off-hand weapon is light in which case (correct me if I'm wrong) you get 0/0 attack bonus and no damage bonus
I'm not sure about double-bladed sabres though
Obviously though you get 2 swings with the 2 sabre and double-bladed sabre options so it's all a matter of whether you prefer to guarantee hitting once or risk missing but take 2 swings - personally I find it easier with single sabre but for my money 2 sabres looks the best and you can have fun with the colour schemes (I had Violet and BLue last time - West Ham colours
