DT: Backline Trouble (H Scotland, H Taylor)

[BomberMan]

I got a backline dilemma. I have never been able to get a decent backline together. 

My Current backline Heath Scotland  aswell as C. Cornes, Goddard, Hurn, Harry Taylor, raines, petrenko, cheney. 

I was going to trade Harry Taylor for either L Harding, drummond, J McDonald.

My other question is should trade H Scotland. Suggestions for his trade include, S Fisher, burgoyne or lockyer. I have the $ to do any of those trade.

Im plaing on hanging on to Raines

Any help and suggestions please!!!
