Unknown bromeliad, speculations welcome

[Rivera]

I don't know what it is. Bromeliads can be hard to ID without an inflorescence present, but I welcome any speculation. 

(Hand for scale)

(Thin, flexible leaves, silvery scales beneath, Puya-like)

The leaves are flexible, not brittle at all. The marginal spines are pronounced but not especially vicious.

It has been growing fine in both wet and dry conditions whether warm or cool (San Francisco). 

(These two were shriveled, barely-anything-there plants back when I received them in the mail, having purchased them on the best known online auction site as Puya dasylirioides from a questionable source. They weren't costly plants, but I believed they were misrepresented so I insisted to the seller that they were not the species and got a refund.)

Any guess what I might have here?

Hechtia sp ( ...H. pretiosa ..or very similar.. perhaps? )  ...or a wider - leaved Dyckia  would be my first guess Genus -wise.  

Agree, from what pictures i can see when pulling up the in question Puya, leaves / way the marginal spines look doesn't match, to my eye at least..

Thanks Nathan. I will update if something revealing happens.
