gweb reminds me of a common occurence at musician jam-nights - 2 guitarists step up to play my Ibanez guitar. The first guy's performance is terrible, and when his song is over nobody claps and he says "These Ibanez guitars suck. I can only play a good guitar like a Strat!" Then the next guest musician steps up and floors the audience with a blazing performance and afterwards he says "Wow, this plays as nice as my Strat!" P5 renderer works great for me. If you cannot get good results and others can, maybe the problem is with the user, and not the tool.
