guess it depends on carry distances and what you want that club to do, I'm thinking of going 7 wood between my 4 wood and 4 iron

As Marc mentioned, it depends on what you need for YOUR game. That is a common gap area, and you have tons of options, and I’d encourage you to work with a fitter to see all of your options.

I’ve enjoyed the U-505 in a 4i and found it very forgiving, especially from the tee. That said, I wouldn’t recommend just buying one unless you feel like it would fill a needed gap in your bag. if you already have a T200 utility build 4i, another utility iron may or may not be the most judicious use of the limited space in your bag.
