Under features and benefits it says (all super slams have)" 1" tubes the 1-5x24mm Dangerous Game has a 30mm tube"
Thats straight from weaver, but like i mentioned, other sites have listed this scope up to 28oz or something crazy! So there is a lot of misinformation about it...
As for zoom preference i guess its just different strokes for different folks kind of thing, i've been gravitating from higher zoom to lower zoom scopes as time goes on...and i think you may be onto something with the tightening of the eye piece!
