I would know how a dead big fly would sink and I think it's a huge

fly fishing it's the only fishing I didn't tried and I think I'll
appasionate very badly, I'm ordering a float tube (Creek ODC 420) and
when I'll have enough money I'll buy a fly rod.
they're so expensive! 600$! I saw a 69$ fly rod and tried to find
differences with the good one and it's too soft, do you think I should
start from that or I have to wait when I can afford a good one?

Ciao, Vittorix. $600 US is a lot to pay for a first fly rod. There are
some good rods that are not too expensive, but without knowing the brand
and model you're thinking about, it's hard to give advice.

Look here

to see if you can find a nice inexpensive used rod and reel. (If it's
primarily for trout fishing there in Italy, look for a medium-fast action
rod, 8.5 or 9 foot, 4 or 5 weight.)

Buona fortuna......
