Jorasses and Trangos are quite similar in terms of the insulation structure.
If you're on a budget and are not planning any vertical ice I'd say get a pair of Mantas, they're very good boots, lot stiffer than trangos and very comfy. next step up would be a pair of second hand Nepals or MtBlancs. These two are very very good, put these together with a pair of good gaiters and you're pretty much sorted. If you think you will push harder (as it usually happens with us once up there..
go for Phantom guides or Baturas. Salewa also make amazing quality B3s for much less money it's just a bit harder to get them in the UK. Mammut Nordwands are insanely light and comfy and they come with the highest gaiter in this class.
dont recommend anything with thin insulation like , jorasses,trangos,phantom lights or carbon rebels, if you find trangos not enough warm , these models wont do the job for you.
good luck!
