Ridersbane Oscar?

So I've had a +spd Oscar for a long time. He's just rocking his base kit for now, but I was wondering if adding Fury and Ridersbane would be a wise choice. Depending how I refine it, either for Mt or Spd, he could have a fantastic offensive spread of 52 and 40(Mt refinement) or 50 and 43, with the ability to counter opposing Lances and a respectable 29 def and a passable 21 res. This is without a Sacred Seal and before Horse Emblem buffs. Which is better though? a final spread of 58/46 after Hone Cav(Is there even a horse outside Emerald Ax or Green TA who can withstand 1 hit from that?) or 56/49(is there a lancer who can avoid his double then with the AI not being smart about buffing? Is Lance Breaker even worth using at this point? If not, what should I put in its place?)
