Default pack a123 m1a

So i went and got myself 32 of the A123 ANR26650 M1A cells, but now i have a problem of how to connect them into a pack. From what i have read, if i were to get them tabbed, the tabbed cells would be current limited to 50 amps depending on the tab used.
http://www.batteryspace.com/A123-Sys...-2500-mAh.aspx
the above link is the website with the stated 50 amp max use for a tabbed cell; they have a link to a 90 amp copper solder bar, but upon emailing to get more info they stated they discontinued it because it was having problems.

That is not the full power of the cell, so the question is how to connect them and get the full 100 or so amps they are capable of?
I saw that one person who used screws to hold the cells together with pressure, and saw that the cells could explode if you didnt allow the pressure relief valve to operate, so that leaves that out.
I was wondering if maybe i put them into a PVC pipe with a compression spring inbetween each cell might work? that way the pressure relief valve wouldnt be 'plugged'. question then is what spring would be suitable of carrying 100+ amps that is also small enough. or maybe you guys have better ideas?
