Dani, I found that trying different style tips was the best way to narrow down a tip to my likes.
You can use any 510 tip. But as stated the inner bore of the tip is what will make a difference.
I try to stay away from wide bore tips. I use a RM2 with the stock airhole. I like a tighter draw.
I have a large variety of drip tips. Metal, pyrex, and delrin. Some I love for the shape and color. Some I love for the draw. It has been trial and error to find a tip that goes well with a certain REO and gives me the tight draw I want.
Might I suggest you try each of the tips you have on your REO and pay attention to the draw. That will give you a base for future purchases.
