I have hot melt in my Driver and FW and I was told (I inquired) that adding hot melt to the u500 would be not produce a noticeable result due to the size of the head (limited space to add enough wax to make a difference). I haven't hit the T200 Utility yet but I do plan to do so with hopes of replacing my u500. I love the look of the T200 vs. the u500. I have no complaints about the u500 but I just love the look of the T200 2 iron.
