Ortofon 309 vs. SME 3012 for SPUs


I am hoping that people here can compare the vintage Ortofon 309 arms to the SME 3012s for use with G type SPUs.

My question is which vintage tonearm is the best complement to a top flight G type SPU? There are a few versions of the RMG 309 tonearm and also SME 3012s (Series I vs. Series II). It seems that the SME 3012 Series I fetches the highest price. I would like to match one with an AE90 or Silver Meister GM MKII SPU.

I use a 309D arm, so I figure it deserves at least one SPU in it's life. Can any users commented on the advantages, disadvantages of the bodied verses N versions of the cartridge. The latter are quite a bit cheaper. Thanks
The Spirit is a very nice SPU and I agree the price/performance is a sweet spot. Most are sold and they are super rare outside Japan. I've only very briefly compared them but I liked my Royal GM more. Once I can get a rear tonearm up and running on my Raven for the SPU I will do a more serious comparison.

In fact thats what attracted me to this thread. I was going to use my Jelco 12" or an FR64fx for this purpose but thought have been turning to alternate 12" SPU friendly tonearms like FR66fx, Ikeda IT407 SME 3012-R, M2-12R or the Ortofon RMG309i. So many options!
I use a 309D on my TW Accustic Raven one and find it an excellent match. I chose it, because Thomas at TW uses it himself and he told me, he felt it gave 90% of the performance of a Phantom at a much cheaper price.
I had did have the RS212D briefly but had to return 2 samples due to loose bearings unfortunately. I ended up with the AS212S as that one in the shop was ok. It was a nice arm on my SP10 with an SPU and various other carts. I changed to the 750L to see what the 12" fuss was about and preffered it with my SPUs. I'd like to try a good 309D yet but the M2-12R and RMG-309i look very tempting. Not sure how much better than a 750L they would be though, if at all.
Latinsamba1,

I am using both arms on my EMT R80 (927). While the Ortofon carries the EMT Tondosen (perfect match) I am using the SME 3012 (first serious, prototype version) for the SPUs, also for the Silver Meister etc. Both arms deliver an exceptional sound quality. The SME is one of the best designs I ever heard and believe me I am in many toneams. Don't go for a series II.
I also have the 309i (Japanese version designed by Ikeda san) which is not a bad one!! Nevertheless I do prefer the original 50 year old Ortofon.
