So for all my bands demos (on facebook, link below) are all done with TMF with the snare blended with Avatar's Rogers Wood snare. It gets good results, but takes WAY too much work to get it to sound good and still imo, it isn't great.
As for the other years products, metalheads was just a stripped down EZX version of TMF, and didn't provide anything new, it was more of a cheaper alternative to TMF so the cheap poor bedroom warrior kiddies could buy it (and thus fatten up Toontracks wallet). The ezmix, I have no care to use, I like doing things the old fashion way and it has never appealed to me. As for the midi libraries, they are good, but a little over the top in technicality. I do think that they should work on hard rock/mainstream metal based groves as well. The libraries all seem way to flashy imo. It would be nice to have some basic groves and fills to help get inspired by to write new tunes, having a drummer play some obscure fills and blasts and is just showing of gets really hard to write stuff or get inspiration.
