Good Advice.
If there is a good head of skimmers at the venue, I would almost certainly target them first as they are usually quite obliging and you can build up a good weight with them. Then as Peter says the snatching line can be used as an infill when you top up or rest the skimmer line.
But congratulations on the weights and final position, practice, practise, practise!! Your next mission should you choose to accept it, is to break the 10lb barrier!!
