Question on Denon DL-103 retipping options and preferences

I have had retipping (and more!) done by Soundsmith, VAS and Needle Clinic.  All of the retipped carts sound great (all of them better than new), but...

Soundsmith retipped my Grado Reference Platinum (saphire cantilever, line contact) in 2017.  Sounds great, but they had to break the wood body apart (crack line is obvious) and they did not mention it at all when I finally got it back over 2 1/2 months later.  Was the work actually done in the US?

NAS retipped 2 Ortofon MC20 Super IIs for me this year (boron cantilevers, one micro ridge, one line contact).  They sound great.  VAS is cagey about turnaround times, though.  First it was maybe a month, then it was suddenly ready.  Outsourced somewhere.  Also, they offered to machine a wood body for one of them but when they received the cartridges they were unable to do it.  And really,  "Friends and Family"?

Needle Clinic has done 6 cartridges for me over the years:

In 2017 they retipped a Denon DL-103R (saphire/line contact) and put it in a wood body (eBay - Stanley Engineering Shop for wood bodies) for me at no extra charge.  It's great.  Turnaround time including the shipping both ways was 8 days (I checked my emails and tracking).   

This year, first my Grado Statement Reference (boron/micro ridge).  Great sound; 9 days turnaround.

Next, I sent them 6 carts at once.  2 turned out to be unrepairable - no charge.  One should have been - a Denon DL-(alpha)S1 with a tiny crack in the suspension missed on initial inspection.  But they told me they would repair it so they did, at the original price; boron/micro ridge.   They put boron/line contact on an Orofon MC20 and boron/micro ridge on a Denon DL-301.  And last but not least, they put boron/microridge on an Ortofon MC20 Super and removed the body (their idea).  That nude MC20 Super is a true reviewer's tool.  All this - turnaround time 10 days.

I recommend Needle Clinic.  Yes you can get quality work elsewhere but not that quickly every time.  And they will answer their phone and their emails promptly.

I went to VAS because I wanted to try a wood body on the Orofon MC20 Super II but... see above.

Plastic, metal, wood, nude - all sound different.  I bet Needle Clinic will put that wood body on for you if you ask, and probably no extra charge.  The old one has to come off to retip it anyway.

Well that is a reasonably sized list of Cart's sent in under the knife.

Changing Cantilever Materials and Body Materials will bring much more to the forefront than the re-tip only.

I'm sure you are wondering why the Original Manufactures didn't become so adventurous and use the alternate options to Voice Cart's for a broader audience to discover their own preferences. 

Personally, my hobby is building and customizing Linn LP12s and tube amps, and ripping LPs to hirez with a PS Audio Phono Converter.  I often run a Sunvalley SV-EQ1616D into it.  I listen via a DAC3 and either Pass XA100.5s through MBL 126s or a Golden Tube Audio SE-40 through Klipsch Forte IVs.

To me, different LPs sound better with different carts.  Probably the most accurate one I have now is that MC20 Super but I have a lot of vinyl that could use a bit of "grace and forgiveness".  The Grado Statement and various Denons (nude and in various bodies) give me options to put an LP in its best light.
