Over the years, I have read much about this 21" DAS Elite riser....It seems to have some sort of majick in it, almost seems like it is the holy grail of risers...So... does it?...Really?...What is it about the 21" Elite that makes folks think that it's so great?...What is the difference between the DAS 21" Elite, and the current version of the 21" DAS Elite that is available from 3 Rivers??....Enlighten me, please.....Jim
