Bapgood yes. As far as draw its a bit airier, i guess i like a more airy draw, but a heckofa lot more vapor. As far as the bit, i got one of the dremel drill bit kits, its the second smallest one, i think 1/32 but dont quote me. I modded the original smoketech rbas this way as well, my wife, who is finicky as heck loves it and stole mine for her other all day juice.
Btw i blocked the air tube with that piece in a carto condom that goes up into the battery connection, just cut it off and it fit perfect, then just cut off the excess that sticks out.
