Don't own one myself but a shooting pal does. I see no benefit over my Vari x III (or other 1" models for that matter) to his 30mm Euro. The only think that comes to mind is negative having to find and buy the 30mm mounts to be used with the Euro's tube!

Trailer I believe has or had the Leuy Euro, I am sure he can chime in with more to the point info for yeah!

Best of luck.
