I have never tried the TSW (but i probably will buy the 54deg). I have the TS1 irons as well and bought the matching gap wedge. I only use my gap wedge for full shots so it made sense to me to buy the matching gapper. If you do a lot of chipping and less than full shots with your gap wedge then possibly the TSW wedge will be better for you in terms of bounce etc. Or you can buy both and see what you prefer!
