There are numerous silver parabolic imported from China. None of them are using soft silver material. And my copy of profoto deep silver 51" is giving me nice light with open tube as close to the ribs as possible. Deep mount kills most of the spill and the inner part of the umbrella is defocused in this position. So it's something like Broncoloc 133 para in defocused position. And I'm starting to think that I need 65" for full body work. And I think that I should move to better studios with Broncolor paras to test them ) So here I'm mostly for some tips from users. Thanks for your reply! And imho true parabolic reflectors are too hard for photography - both briese and broncolor are scattering the light very much, from true parabolic reflector you'll see the light only from one point of the reflector and both of those are not even close to that. Therefore I don't care about the naming but care for the light quality.

I am looking into the para options for Broncolor (I now use the Siros L). As I regularly travel to locations, it also has to be portable (sort of), which limits the choice to the para 88 and 133 (both can used with the Siros L).

Maybe have a look at the following video by Karl Taylor.

I can share my experience with you, as I have both. The 88 is really a headshot modifier. The 133 is obviously larger and suited for more than just portraits. You could do full body, but it's actually a bit small for that as well so you'll get falloff. It's also easier to get the distinctive Para catchlight (with the black centre) with the 133 and Siros. The 88 takes up a lot less volume in total so it's more feasible in small spaces.

With a Siros L (especially 800), expect to use a really sturdy tripod, preferably with casters, as they get very front-heavy in the defocused position (especially the 133 because it extends further). The focusing rod is extremely strong and can carry the weight just fine, but it's just all hanging out in front. For this reason I use it with a Move/MobiLED 95% of the time, instead of a Siros.

Final tip, which you won't get anywhere else: you cannot mount either 88 or 133 to the Siros as a "reflector" (without the focusing rod). You can on every other broncolor head, but the Siros body doesn't fit inside the Para flange for direct mounting.
