I was just having a gander at your charming resin infusion starter kit, and was wondering if it would fit my needs. I've only ever done wet hand layups in the past, so jumping straight into resin infusion vacuum bagging is a pretty big step for me. 

Aha. Thank you all for your advice. it sounds like I had better stick to laying it up by hand without the vac then. What resin would you recommend in that case? Thinking of just a single layer of 200 gsm carbon all around, although I am tempted by the jute or flax maybe? Sorry to keep inflicting myself upon your wealth of knowledge like this...
