I wouldn't use an 8 degree orb for a wide trine to Pluto. That's really stretching it.
Pluto is just a dwarf planet. I only give it a 3 degree orb compared to the planets which I give a 5 degree orb. I am talking about natal. if we use an 8 degree orb for Pluto, then we can do the same for Eris,Makemake,Haumea which are also transneptunian dwarf planets. The same orb could be used for Sedna,Quaoar,Orcus,Varuna,and Ixion which are transneptunian dwarf planet candidates.
there are over 70 transneptunians that meet dwarf planet criteria. We can use 8 degree orbs for those too.
You probably have other transneptunian aspects tha make you relate to tha wide orbed Pluto aspect.
You might have Moon trine Pluto within orb in Right Ascension.
There could be a midpoint picture.
