Morch DP-8 arm on a Helix Two turntable

Hello everyone. I am exploring putting a Morch DP-8 tonearm on a Helix Two turntable. I would like opinions from people who own the DP-8 specifically on how easy is to calibrate, how is its tracking and how accurate are the low frequencies. What is your accompanied cartridge(s)? I assume your system is capable of reproducing accurately instruments below 50Hz. Thanks in advance for taking the time to respond.
@dover thank you for clarifying, the Morch DP-6/8 is a dual pivot design and share some similarity to the knife edge bearing in vintage SME 3009 arms.
The DP-8 has VTA adjustment that isn't on their lower models, can you share your experiences on how well this work. What you like/dislike. TIA   
Can the OP share with the class...what arm did you decide on?
My original approach was to try and minimize the initial acquisition cost by using a less expensive tonearm than the Schroder CB11 or CB9. I used to have the UP4 long time ago, it was good and liked the interchangeable armtubes. However, I was apprehensive of the DP8 design and compatibility with the Helix Two. Finally, I decided to use the Ikeda IT345 CR1 short tonearm that I have on hand to start with and get a second armboard pre-drilled for the CB11. I will buy the CB11 at a later point when the financials allow and if deemed necessary. It is important for me to be able to change on the fly cartridges as I have multiple cartridges that I like to listen to (Skala, Frog, Orpheus and A90). Just for reference, the rest of the system is Ypsilon (Phono and Integrated amp), B&W 801 S3 Matrix and Yamaha NS 5000 speakers, Ideon Ayazi DAC and cabling from Ypsilon and FM Acoustics. All the best to all and thanks for the lively discussion.
Thanks for the clarification, Dover.
Hi -

I set up the DP8 12" - comments as follows
Cartridge alignment easy with removeable arm tube & you simply line the stylus tip up with the edge of the headshell if you have installed the arm at the correct pivot to stylus. I checked this on a Feickert protractor.

Tuning the eccentric lateral side weights - I found these fiddly to accurately dial in.

VTA adjuster

The vertical distance between the plane where the tonearm is mounted to the plane where the record is placed should be between 28 mm (1 1/8”) and 40 mm (1 9/16”).

Fairly course & a bit clunky - big issue I had was the platter to armboard range is narrow and on the turntable I installed the arm on I had to make a custom bronze base to get the arm into range. Without doing this the VTA adjuster has major issues.

Soundwise I did not hear the bottom end punch that I expected from the reviews. The Dynavector & FR64 have considerably more punch.
The sound was well balanced and reasonably good - on a par with a Helius Omega which was also tried.

I like that you can buy different armtubes to optimise the effective mass, I also like that you can convert the arm from 9-12" without buying a new one.

Downside of spindly armtube was that I did find it sensitive to vibration.

I think its a good arm, particularly if you get a good deal, but not at the level of Kuzma 4Point etc.
