smirch,
i think i found the NACTO site on my way to finding CRO.
what was special with CRO was the depth of bases available. i'd made the Kris Dhillon (KD) base slightly modified for many years but could not believe how much better some of the bases are on this site (some meaning that i've not tried that many and not sure about what i haven?t tried - i list rajver, saffron and ifndforu as the ones i've settle on, the rajver & infindforu have coconut in the saffron doesn?t, i only say this as some people are not keen on the coconut, they all produce top notch results).
