As I said on a previous thread - the Ganders that are split for Buff are invaluable to maintain size, type and vigour, so a high quality Grey line is well worth keeping alongside the Buffs. Due to the scarcity of Buff Ganders in the UK it's impractical to breed splits this way.
We have used our Grey Ganders to Buff females to produce our Split males.
