Hi! i'm new in this forum!! nice to meet you!! :D....first of all, i have started to fishing 7-8 months ago, and i love spinning!! so, i have a question, i'm thinking in buy a new rod, Ugly stik gx2, i saw a lot of videos and it is unbreable!! but i would ask, can i use lures of 1-1 1/2 oz with this rod? because of the official website, the 9" rod could use max 3/4 oz, but i saw so many video of this incredible rod, that i would like to use some lures heavier, but i'm afraid to break it :(....thank you so much!! :D

Typically spinning gear made for bass fishing isn’t designed for lures that heavy.  It’s not necessarily the risk of breaking the rod while casting.  It’s that the rod will not cast the lure easily.  Also there may be issues working the lure as intended. You might want to consider casting gear.  If that doesn’t appeal to you, you might consider a lighter variant of whatever lure you have in mind.  Unless you are talking about bigger swimbaits, a lighter version likely exist. 

I broke a rod on a fishing trip once and had few choices for a quick emergency replacement except for a GX2 6'6" Medium spinning rod.  It's easily as stout as other brand's Medium Heavy.  From my experience, you could put bigger lures on without breaking it.  Just be prepared for sore arms by the end of the day because it's a log and weighs a ton.

Always follow the manufacturers recommended lure rating and you will be fine.
