Koetsu Rosewood Vs Rosewood Signature Vs HANA UMAMI RED advice please

I ended up buying an Acoustic Signature Typhoon, with a 11" Kuzma 4Point. Now the question is which cartridge I get.
I have a Hana E and M in my current VPI and really like them, but I looking forward to test something else. I like detail without much in your face(?), soundstage and some hint of warmth. 

I saved $4K for a cartridge and I am getting 25% off on any cartridge I want, and do not need to spend the $4k.

I am open to other brands, except Sound Smith which I had in my Bergmann Galder and did not like at all.

My system for the Typhoon is composed of
Tannoy Kensington
Pathos Heritage, or Primaluna 300
Manley Labs Steelhead 
all powered with a PS powerplant.
Thank you
I have a Kuzma Ref 2, with a Ref 313 VTA... Perhaps not quite to 4 Point 11" level, but similar mass and an arm I'm very happy with. I was in the same price range as you, and have an MSL Hyper Eminent on the way. I bought it last week. I spoke with someone who has experience with the MSL Eminent EX (base model) and the Unami. He said the latter is more of a detailed, forward sound than the similarly priced base MSL. The gold body Hyper is actually described right on the MSL site as being a bit more forgiving. It's supposed to be very dynamic, but not the last word in detail like the higher priced Ultra Eminent EX. Please keep in mind he likes the Unami very much, and his comments were in direct comparison to the base model My Sonic. I find Dovers advice really interesting, as I have also heard great things about Phasemation. I must ask Dover, what LOW priced Air Tight cartridge are you referring to? The base model is around $8K US. (-: 
Was told Kansui/Kuzma may not be a good match.

Dover said: "The VDH cartridges can work with the Kuzma 4Point11, but they need to be adjusted by VDH for the higher mass (18g)."
The Kuzma arms are medium mass, aren’t they. Mine is 13 grams, and I thought that was true with the 4 Point 11".

All of the posters here strike me as a seasoned, been there/done that group. I’d make a bet we all try to steer clear of the Hi-Fi sounding cartridges, and value tone with a nice fleshed out human sound. I know that’s what I crave. I was also considering Koetsu and EMT. I’ve owned and enjoyed the former, and still own and enjoy the 75. But I thought it was time to try something different with the MSL. While I’m sure their five models share a family sound, it’s my understanding that they do differ. Particularly the two gold body offerings. Again, there is a pretty good description on their website. Wayne Garcia recently reviewed the top MSL Gold model along with the Koetsu RSP. Other cartridges of interest, like Etsuru and Sumile, were simply out of my price range. I hate to pile it on, but two others options I found interesting were the Musikraft Nitro, and top line Charisma model.
perhaps in honor of working in the USA consider a Grado ? i am on a quest myself…..best to you.
i understand the first world problem of maintaining two high end analog systems in different locale…..
Thank you to all of you! I just bought the Koetsu Signature, hopefully I will not lose more sleep over it.
Although I was getting very good prices for other cartridges, I  think that at $3600 I can't go wrong. Now I need to sell my VPI to make room for the Acoustic Signature in my rack.
