Referring to Opeth sounding better with the 'organic' sound, i think you are right... But i also think that modern day drum-modules sound so good that 95 out of 100 people here won't hear the difference with a real kick...
And again, a trigger is as much an advantage to the drummer as it is to the sound-engineer! No hassle with mikes, cross-talking between other mikes, endless sound-checking to give the kicks more definition, compressing/eqing, damping, etc..
If you don't disable the velocity (the term which defines the force with which you hit the skin) on the module, you, as a drummer, don't have any advantages whatsoever.. You still have to hit each drum with the same force! And, on the downside, if you trigger, faults and sloppy timings will be way more audible...
Same as the before mentioned piano.. You can bring a real piano on stage, which needs escessive miking, tuning, etcetera.. You can also bring a digital piano on stage, hand the sound-engineer 2 jack-cables and you're good to go! And, especially in live-situations, people won't hear the difference..
And yeah, i wish i could play a song like Masters Apprentices, damn!! But then again, check the media section (the 4-8-06 jam vid is INCREDIBLE) on
The Derek Roddy site, this guy is much, MUCH faster and easily keeps that speed up for a whole 2 hour show... (To me, Derek Roddy is the best drummer there is.. Not only able to play ultra-fast Deathmetal, but also blues, jazz, fusion, you name it..)
But i'm going offtopic here

I'm not pro- or anti-triggers, but it bothers me that a lot of people call drummers with triggers bad.. Or lazy.. (Not happening here yet, but i've heard it soooo many times..) Some people don't know exactly what a trigger does..
A trigger, on impact of the skin, (it 'senses' the vibration) sends a pulse to the connected drum-module. The pulse contains information about the impact, like velocity. The module receives this and plays the selected sample on the right velocity/volume. That's it. It is not a magic box which makes everyone a superdrummer! As i said, if your kicks are really audible, sloppy timings and errors will be way more clear, so in a way, you have to be a really tight drummer to make triggers work to your advantage!
Every module has an option to exclude velocity-data, so that all samples sound at the same volume, no matter how hard you hit the skin. This is the only way a drummer can "cheat". But what would you rather have? A acoustic drummer who plays really fast, but you can't really tell because the kicks tend to drown in the mix, of triggered kicks and being able to hear everything the drummer does?
And again, end of rant, haha.. Not trying to accusing people of ignorance or something, just trying to explain some stuff about triggers

Definately no offence meant to anyone! *hands beers all around*
