If $$$ is a concern, keep saving a bit longer and invest in good products that will outlast the cheaper. If you think about it, its a waste of money to buy cheaply made stuff only to replace it a season or two later down the road.

Also I beleive the harken carbo provide the best holding power to weight ratio. I know for a fact harken carbo mainsheet triple blocks are lighter than ronstans.

food for thought
