I'd say Coastal or Coastal X yep.
On the size thing

LOL
OK males & females can get the same size, heck males can even be bigger.
Females are typically bigger as they are fed more by breeders as they require it more than the males do. thus why females tend to be bigger its all in the feeding.
The whole its only 6ft so it must be an IJ thing is a crock of crap as well.
IJs can & will hit 7ft+ easy just like ANY other subspecies will.]
Whether they are given the opportunity to or not is the question.
Too many misinformed folks or outright scumbags breeding babies way too young & way too small thus why you see all these tiny lil "breeders" out there.
Female carpets require a full 4 years to fully mature & be given a chance to reach their full potentials size wise.
Same thing happened with Carpets as did with the stupid BPs as morphs became more & more trendy & marketable (IE CASH!!!).
Folks lowered all standards for properly raising these animals & set the bar as low as possible.
I personally know of people breeding females Jags at 1.5 yo, but hey they were 7ft 7 eating jumbo rats already

can you say seriously POWERFED Boys & Girls? I can or there are these folks that think 1500g & 1.5 yo are acceptable standards for female Carpets!!!
NOT acceptable for stupid BPs even let alone Carpets!!! END RANT Mark LOL
