We used to have a mix of Acute and D1/B2/B1, etc., before starting a move to strictly Acute & Pro Head kits. The recessed head does effect light spread in larger softboxes and in BDs. It also limits the effect of some Profoto reflectors.
You can use a B2 or if adventurous, a B1/D1/D2 (due to weight) in a Bron Para 88, but you need to add an app. 6" 5/8 baby pin extension to the Bron's mount to get the recessed 77 deg light spread to fill the para. For a larger Para, that extension may need to be longer - making the unit even more front-heavy.
The optional dome (for other than the B2) helps, but only takes the unit so far when compared to the 'normal' exposed Profoto tube.
However, it makes for more secure packing, easier, more compact grid use and does a great job protecting the tube in the case of mishandling (don't ask).
