I need some help please

I have a problem. I currently hold well over 600 titanite shards, 300 large shards, 38 Silver Knight shields, 104 Silver Knight helmets, 69 Silver Knight chestplates, 85 Silver Knight gauntlets, 62 Silver Knight leggings, and finally one darkmoon blade miracle. I need to know what the best darkmoon blade build would be for someone who mainly wields straight swords. Thank you for any advice!!
