Hard Decision On Getting A Radiant Melee

I don't know why this is so complicated for me to decide on. That is why I am making this post to get some opinions. I am having a hard decision on whether or not I should. Salvage/Sell my current SL 5 5* fully pearled bow (PD / AS / HR / CD) , SL 5 5* fully pearled face (MH / CD / PD / HR), SL 5 0* fully pearled hat (MH / AS / MH / HR). All of this probably costing a total of 130k flux (not sure). With this flux buying a radiant melee. Or with the 3 pentas start to upgrade a SL 4 5* melee that I have (all I need is 2 quad and purifying flames which I don't mind farming for.) and upgrading the melee to radiant. I would like to get some opinions on these decisions. After getting the radiant melee I would start farming a decent hat and face again.

Thanks everyone for taking the time to read this thread! :)
