Visa/Passport Dilemma!!!!

[Inside]

So im an Aussie, heading to Europe for a year of solo backpacking

Fortunantly for me i qualify for Italian citizenship and therefore an Italian passport...................which is !@#$in awesome


So i got the ball rolling on Italian citizenship in january (i leave May 20th) but its still not finalized, they told me today that they should know if im sweet in ten days.
So i thought "sh*t i better get a Visa, just in case" but it turns out that UK Visas have gone up from $220 to $580.............................this makes me wonder, should i


A)stuff the Visa, hope i land the Italian passport and if i don't head to the UK as a visitor, and then sort out my italian passport in Italy (this will take some re-arraging of flights, to ensure i leave the UK in 6 months, which i will easily anyway)


B)Suck iy up and pay the $580 knowing all too well that my passport could be sorted in a couple of weeks and i just flushed nearly $600 away
