Time to choose: Baerwald, Lofgren, Stevenson ?

I’ve managed Dr.Feickert Analog Protractor for a decent price (build quality is superb, such a great tool).

Time to play with Baerwald, Lofgren, Stevenson alignments on my Luxman PD444.
Need advice from experienced used of the following arms:
Lustre GST 801
Victor UA-7045
Luxman TA-1
Reed 3P "12
Schick "12

Baerwald, Lofgren, Stevenson ? What do you like the most for these arms?
Manufacturers recommend Baerwald mostly. 

Dedicated "7 inch vinyl playback deserve Stevenson alternative, maybe?
Since it's a smaller format than normal "12 or "10 inch vinyl, it's like playin the last track's according to position of grooves on '7 inch (45 rpm) singles. RCA invented this format, i wonder which alignment did they used for radio broadcast studios.   

Thanks

@fleib Feickert’s step-1 of the Stevenson’s point for overhang is exactly the beggining of the groove on 7’inch vinyl. That’s what i meant. The null points are on the left and right, and only inner null (by Stevenson), which is step-3 by Feickert, located in the end of the musical information (groove) of the 7’inch vinyl.

Chakster, I assume the end result would be the null distance for a standard alignment, whichever it is, the same as listed on page 2.

Now that I think about it, perhaps the UNI-DIN nulls would be most pleasing on a 7".  It will have much less error at the end, compared to Loefgren, and be better than Stevenson in all but the end. Nulls are at 63.3 and 112.5mm.  Check this out:

You can get a protractor that is just a calibrated straight line. It's called Chpratz:
