If you look at http://naturalstudio.co.uk/ns_kit7specs.html you'll see there Kick drums: - Gretsch USA Maple kicks - 22", 20" (a multitude of tunings, from open and ringy to punchy and fast). - Sonor 16". - Gretsch USA Maple 14" tom played as a kick! So I think you should consider buying full (real) nskit. It's no very expensive. Lucky you know exactly what you want :), and I think they (hmm, him?) will reply all your questions regarding sound. I'm not using it (yet), but plan to buy it when/if I will need acoustic drums. Though, I just do not know any other acoustic drum samples set :). Regards, Dmitry.
