cool, thanks james. i assume "flowbench" is the brand or something of it?
I'll have to find what brand my head shop uses and see if it's the same...if it is well that's easy, if not i'll have to try and find what the difference between the two are...like the "flowbench" might give 10% higher numbers than xxx machine etc...
getting all the info today (fiancee is picking the head up for me later today)...will post info as soon as i get it
