tube placement

[jenga]

Ive just ordered some new t5 tubes
1x osram skylight 880
1x osram 840
1x sylvania growlux
my housing is aluminium and I have lined it with plexiglass mirror for reflection, is there any advantage in placing the tubes in a particular order, front to back?

The only real benefit is the order which looks best to you.
