Do You Have a Favorite Disk to Set VTA/SRA?

Dougdeacon, I believe that adjusting VTA to every dorn LP every time is rather spiritual masterbation than proper setup (xc'uz my poor Friench) unless it's TT that has the feature 'on flight VTA adjustment'(adore Technics 1200 for that).
It's especially pain in anus when yo try to do that with 7" records or flexis
Other then that, Ebm gives advise much closer to RW(real world) if you don't have majority of 180...200g pressings. Another words, use the most common size and calibur record from your collection and b done and don't jerk it every time(that's RW).
As far as sound testing of VTA goes, I use Dire Straits "On Every Street" UK pressing or Mark Knophler's "Nottinghillbillies" Italian pressing.

Dougdeacon, do you have 7" records? They have also different thickness. For what it's worth even with on-flight VTA it's insane and sick and not normal. Try to promote your strategy to Rega owners LOL!

New generation tonearms should have VTA and other adjustments with remote control, so you don't have to leave a sweet spot.

With help of headphones you don't have to jog between sweet-spot and equipment stand.
