6 KC is ONLY advised if you are prepared to lose Deaths, and want to get nothing but chaos runes as your source of income. I am currently doing 15 KC runs, and over 6kc, it only takes 3-4 minutes longer, but the blood runes is worth that 3-4 minutes. You also get higher chance of Death rune in the chest so you recycle more efficiently (you may lose minds, but it is very cheap to replace, 300k cash will get you 15k minds no problem and it will last a hell long time) Ectophial is pretty much your only option of panic button/barrow restart button if you do not have a house with an altar AND Kharyrll Portal (which gets you straight to canafis), if you somehow got them, try and find a person with Mahogony Demon Lecturn and make 200 or so Teleport to house tablets, and trust me, it will make barrow runs a lot easier. Otherwise your stats should do fine. I still recommend you to pray on ALL the brothers on the first few trips to get yourself farmiliar with them, then you can try not praying against the 2 lesser melee brothers (you would still have to pray against ahrim, since your magic and defence is low)
