I made a wing mirror today.  Went fairly well.  Perfect vacuum from the off etc.  However, the resin shot through the mesh pretty quickly.  The surface is a bit dull and pinholey.  What I observed was a quick infusion through the mesh and, after clamp off, there seemed to be some fine bubbles come from the stack.  I assume that the resin shot through the mesh and the fine bubbles was the resin infusing into the cloth (1x660g carbon).  This leads me to believe that if I could slow the rate of infusion it would infuse into the cloth at the same time as it flows through the mesh.  Now I think I could do this by either only opening the clamp a small amount or by infusing just through the peel ply (its a small part).  Does this sound like a reasonable conclusion and course of action?

Answered my own questions.  yes you can infuse through peel ply and yes it is FAR slower (as you'd expect) and yes it does give a better result.  Less aerated resin at the flow front and far better finish.  I guess with a small part the resin flow is best controlled by the tube clamp rather than the flow medium.  I suspect that with a large part flow in the fully open tube is the limiting factor.  It'd be interesting to see if there's an optimum rate for flow giving good finish but good productivity.  From my limited 'feel' I'd guess at 10cm / min across the part?  Any further 'finger in the air' feelings?
