Personally I don't like the combined house / start setup. Not so much for lack of starting power (rarely an issue if the house bank is big enough), but because of the voltage dip all of the electronics see during engine start. Better to keep that isolated when possible.

I've got 3 banks personally. House (2x L16), Start 1 (grp 27), Start 2 (grp 27). House is isolated from both start banks, connecting them would require jumper cables. So house is an on/off switch. Each engine and the generator has a 1/2/both/off switch to select its power source. Normally the port engine starts from Start 1, starboard and the generator are set to use Start 2. Makes it hard to end up in a situation where I can't get something started and it also keeps house loads separate from cranking current.
