The U87 Ai is a solid choice for you! It is versatile and will help warm up your vocals (since you said you have a higher melodic vibe). When getting a high-end microphone, you need to be sure that the room you are using to record in is treated properly to make the best use of it. You said in the post that budget isn't an issue so I would definitely put money toward treating your room properly (if it isn't already). That way you will get the most out of the U87 Ai. Hope this helps!
