The reduced pattern Hog Isles from PMHerps is the only genetic Hog morph that is PURE Hog Island.
There are Hypo Hogs, Sunsets (Super Hypo Hog), Hypo Hog DH Ghost, and a few other crosses with morphs or locale crosses.
I know of crosses with Colombian BCI, Suriname BCC, and Peruvian BCC.
If you are just going with Hogs because of their smaller size, but want to look at other colors of boas, take a look at a few of these locale: (All are the same size or smaller, on average, than Hogs)
Cay Caulker
Crawl Cay
Corn Island
Sonoran
Nicaraguan
Tarahumara Mt.
Costa Rican
Panamanian
The above are B.c.imperator. But, B.c.sabogae, or Pearl Island boas, are also small.
That list has a variety of natural color varience, and a number of morphs as well. Just make sure you get PURE animals if you want smaller boas, a lot of these have been crossed with Colombians, or unknown lineage animals.
From the Sonorans you have Leopard boas and Sonoran Hypos (the Supers look like nice Hogs). From the Nicaraguans you have T-plus Albinos, Hypos, Ghosts, Type II Anery, and Motleys. There are also Blood boas, but make sure you find the full lineage and the adult size of the parents to the snake. The morph originated from El Salvador stock, and I do not believe there are any pure El Salvadors that are in the US that are NOT Bloods or Pewters (Double homozygous Blood and Type II Anery). Bloods from the Salmon line seem to be small as well, and you have the added option of Bloody Salmons. But there are some with a lot of Colombian blood in them and they will likely grow larger.
