No idea about burms as I have never owned one but my experience with a sd/d retic is they are work. Caesar is about 9 feet and a 37.5% sd 37.5% dwarf. He is a handful but in an inquisitive way. Never took a shot at me.

But imo retics are pretty neat and a very interactive snake. Only difference I see is the size caging and food between fullsize and sd retics. The price is a big difference though between sd and fullsize retics.
