Roland,
I found with the e-blade that trigger adjustment makes a lot of difference as to how fast you can fire it.
I spent a good couple of hours getting the pull down to about a 1mm and then I could walk it ridicoulousy (sp!) fast.
The e-blade manual actually gives some good info as to how to fine tune the trigger, but you will also get a far quicker set up by reducing the ball in breech settings right down (the amount of time it pauses waiting for a ball to enter the breech etc). Again, info on how to do this is in the manual...
