These typically have less overload capacity than conventional junction diode rectifiers. There will be a current surge upon cold start, and the rectifiers have to be able to withstand the surge without damage.

I would install the largest bridge that will fit.

Beware, though, that the forward voltage drop through the rectifiers may also be higher and the filament voltage may be reduced as a consequence. It is not clear to me that the filament voltage service generates enough electrical noise to make the fancy rectifiers worthwhile.
