In the process of setting up a LP12 for a ET2.5 tonearm. Is the aluminum mounting base a noticeable improvement?

Mounting the tonearm via the current pivot hole does not work for a couple of reasons:
a) the ET bearing spindle is not sufficiently long to allow the tonearm / cartridge to reach the outer diameter of the platter. The mount point, by necessity, has to be approximately half way down the arm board to allow the tonearm to reach the outer edge of the platter.
b) The Linn pivot hole mount point pushes all the tonearm weight to the outer edge of the suspension. This is a necessary evil with traditional tonearms. With an armboard midpoint mounting the tonearm weight now rests between the two suspension points supporting the armboard/platter which seems like a much better solution.
Please see the picture below.
At the top left is the original Linn tonearm mounting point. This is where I first mounted the ET tonearm.
The new ET arm mounting point is called out. I prefer this mount point because it is between the suspension points and is directly above the point at which the sub-chassis connects tot he armboard.
