Efficiency: Pumping in a Tight Pump x in a Larger Pump

[jcarrier]

My pumping experience has always been with a X30. For a few months recently I got to a point where i'd reach maximum length in it and basically also fill it in terms of girth. Pressure build up inside was pretty great, but I felt that if there is no room to expand further, then probably i would not be able to grow further with it.
So I got a X40, which is by the way much larger.
With the X40, I'm not hitting the walls of the chamber and there's is a good space on top lenghtwise, but still am getting good pressure - nothing incredibly relevant, but still enough pressure.
So there question is: for growth and permanent enlargement, which would be more effective: pumping at great pressure in a tight x30 or pumping in good pressure in a x40?

I dont pump but it would seem to me that if you're packing the old tube, its time to go with a larger one. Are you doing any routine other than pumping?

Packing the tube completely length and girth stops the potential for further growth. If you pack the sides but have room at the top it can help with length. The bigger cylinder should help most with girth. I often use my old cylinders in size increase chain fashion. Start with the small, pack it, take a rest edging session to gain good blood flow, use the next cylinder, pack it, take an edge session for blood flow, next size cylinder which I cannot yet pack. I will pack the large cylinder I assure you, I just Dont know when yet.
