All good research NTE....One thing to keep in mind with e-61 over a Silvia for example is that 4.5kg of brass in the group is more temp. stable than say a Silvia group...This implies a slower change in temperature...
The well built HX machines are inherently temp stable. If manufacturers botch, omit or shortcut the R&D stage though, you can get a cranky, hot machine which is way more challenging to work with.
This is where good advice and/or a road test come into play ;)
