I use a single 2mm. The ideal would be 3mm. Does not exist. 4 mm raises the arm at the pivot point too high. Gandy himself says is preferable to be a bit low.
VTA is not really that important except if you have many 180 or 200 grs records badly warped..
The most important improvement you can make is to get a decent constant rotational speed. You must replace the polymer sub-platter by an Isokinetic (or Groovetracer, if you are in America). Even if you have the TTPSU the Rega is not speed accurate. And the plastic subplatter attracts dust to the belt. Complement that with the Rega white Belt
Buy a standard (not the Rega Version) Michell clamp. This comes with a felt washer. Keep it in for normal records, remove it for 180 grams or over. It's the equivalent of raising the arm pillar pillar about 1 mm. Get rid of the felt mat for a further rigid coupling of the record to the platter. I found Herbie's Mat which is silicone foam a good one.
And then forget VTA. Make sure records are immaculately clean, by using a carbon fibre cleaning arm and connect the wire to the ground of your preaamp. This carries the static out which prevents dust atraction, and this way your expensive Glider stylus will last maybe one year more.. Nowadays they are hard to find.
