but most people use the JWT cams if you look at the specs of his cams closely you will see that they are a very good cam. I especially like the JWT 400+ the problem with Tomei and Jun cams is that the base circle is smaller. The JWT is a safer choice.
And the Tomei and Jun are two of the major players use loose VTC with and most rare as well. The Non high lift cams from tomei I believe maintain VTC.
