It really comes down to the what you need and the kind of shot/performance you are wanting to get out of the club. I am a good example of someone who prefers the FDI. I play the #3 and #4 and have them in my set of TS4’s 5-GW. they provide the distance gapping I need and I can control the trajectory better than with a traditional hybrid like our Tour TC. I hit those well, but I hit them higher, which I really don’t need. I do have a gap between the FDI #3 iron and my only fairway wood (TC #3 fairway), but I can actually throttle down the #3 wood when necessary. Probably could and will add a #5 wood to fill the distance gap between the FDI #3 iron and the TC Fairway #3. The more traditional shaped hybrids like the TC’s are designed to hit the ball higher than comparable long irons. My FDI’s are blended lengths into my set, so standard #3 iron length and #4 iron length. The head weights are kind of set up to do that with the FDI’s. You can do it with TC’s as well, but just be aware of the head weights when determining what length you are going to make them. Most tend to make traditional hybrids like the TC’s a little longer, maybe 1/2″, than the long irons they are trying to replace. Again, the length you make them should be driven by what fits you and what provides the best performance and distance gapping you need for your set.
