Jon Michell used the SMEV in the development of the Gyro/Orbe. I've always used the SME V with my Orbe SE. Many users have also raved about the Orbe/Graham 2.2 combo as well as the Gyro/Moerch combo. I've acquired an used Graham 2.2 about 6 months ago, but have not had a chance to switch over to give it a listen.
As other have indicated, weight is a concrrn. Some can be compensated with a lighter armboard. Contact the distributor and the arm manufacturer to make sure they can supply an armboard for the particular arm. Some arms like the Graham Phantom and Dynavector are just way too heavy. But I've seen a guy in Singapore with the Orbe SE/ Dynavector combo. Not sure how he did it.
