cat sx shock springs

[danny the elfman]

hello, i got some cat sx (not the big bore ones) shocks for my mad monkey, and they fit very well, and are very smooth. But i was wandering what springs fit? If i get the schumacher springs, i get 6 springs for £20, these http://www.m-k-racing.com/product_in...oducts_id=5820. But if associated ones fit then i get 5 pairs for £11. these http://www.m-k-racing.com/product_in...roducts_id=386. would getting the schumacher ones be better? and if i just decide to buy one pair of springs for the front and back, what colour should i get? thanks for reading
