Proper cartridge angle for Shelter 501 using tonearn height adjustment


Running a Shelter 501 on a Technics SL1200 turntable. 
I set it up with the bottom of the cartridge parallel with the record surface.  It is also aligned using a Turntable Basics mirror protractor which puts the cartridge exactly flush with the front of the headshell.  Is level the proper placement?  Or should the cartridge be at a slight angle? How about the arm?  Should it be level or maybe slightly higher/lower in the rear? 
Thanks for any input. -John

I have the height set at 0.8mm from "0". It can go up as much as 6mm. This puts it at near min.
Tracking weight at 1-1/4 grams, anti skate at 1-1/4.
I am installing a Sumiko headshell in lieu of the stk Technics. I figured as long as everything is getting re-aligned I should get some input. I see on one of your other threads you run the extra weight. I have never had any tracking or skipping issues, ever. Is the added weight for sound or tracking?
FYI: The table has the KAB Cardas re-wire and RCA adapter plate. I believe he stuffs the arm with a light amount of cotton also.
Thanks, John
The 501-II has a recommended vertical tracking force range of between 1.4g and 1.9g.  You could experiment with different settings within these parameters.  It is kind of an odd bird.  super-stiff suspension that likes a relatively low tracking force.

This cartridge does seem to 'like' heavier arms.  You could try mass-loading the headshell end.  And the Sumiko headshell is a good one to try.  If you have the HFN001 test record you can use the arm/cartridge resonance tracks as a reference for your 'mass adjustments'.  When adding mass I tend to shoot for a arm/cartridge system resonance happening at 9hz.  9-10.

The 501 type 2 is known to find its best tonal balance and focus in a tail-down attitude.
