I share your sentiments (sadly).
I believe in picking combinations. If Morne Steyn and Peter Grant are the two flyhalves, then Hougaardt and Duvenhage must be their scrummies.
Bud your last few posts have all been worded such that I agree with your points, but disagree at the same time
Taking them in combinations means a potential better 'understanding' between those players, but I wouldn't take the combination as they're not always the best in that position. All the players would technically be trained under coaches they aren't used to, thus the 'understanding' could be formed by any good pairing?
PS. Forgive my spelling on his name...
