CS Soubds usually sound really good. But whatever add on I buy. I get the TSS sound packs for the real effect. The TSS 732 pack is only a couple of pounds so is a good investment if you find that CS isnt up to scratch. Overall the base pack Sounds are about 98% accurate. James

The default sound pack that comes with the 737 is the TSS sound pack. :) and i love it. i also have them for my 707 and 767GE.
