Generally, thicker materials more easily crakc from heat/cooling
expansion and ocntracatin than thinnner materials.  More imporant is
what the plastic is made of and how it is used.  Aluminum expands more
than plastic.  Could be that JBJ's problem is the the aluminum expands
more than the plastic endpieces can bear.  That would just be a faulty
design.  Not the first comlaint I've hard about JBJ.

Pretty sure Oceanics are the same as used by All-Glass.  The PCs are GE
bulbs and Oceanic generally makes high quality stuff.
