Who to trade out!

[Carlton123]

I have 3 trades left and nothing really in the bank, I'd like to get Fyfe as my final forward and I might make the top 4 if I get him now. I'd have to double trade but with heppell to cover enright and gibbs when they have there finals byes I think 1 trade and about 40k is okay. My dillema is whether to trade out didak or mzungu who are both virtually the same price and average, I think dids is better but is more likely to be injured or rested and I want some good cover, who should I trade out or is 1 trade not enough?

From that brief summary. I trade isn't enough. Hold them for finals.
