needs in some cases exceeded what the SQF could pump so will be trying Lorentz
for the first time.&nbsp; I was hesitant after hearing some unfavorable things
about Lorentz but have been told that the latest versions have the problems
worked out.&nbsp; I&#8217;m afraid I don&#8217;t recall what the original problems
were supposed to be but I&#8217;m sure others on the list will contribute their
experiences.&nbsp; It will be interesting to see how both systems hold up in
