more importantly i have considered tan in more detail - it looks fanTANtastic thus far. i have more research to do in relation to it over the next few days, but early signs are good. as and when i have completed my review of it, i shall submit it on here. or alternativley numpties can ask me any specifics.
the post by lb in which he highlighted tan to me serves to reinforce the purpose of this thread - to exchange views of undervalued situations and allow advanced non numpties to benefit from them.
