RSi 1 Irons

Face Slot Technology for Distance and Forgiveness

New Face Slot technology on the heel and toe of the irons provide uniform flexation across the face at impact, generating higher ball speeds and protecting distance even on off-center hits. Combined with the successful Speed Pocket Technology in the sole of the irons, the RSi 1's are fast, long, and extremely forgiving, culminating in high MOI playability and impressive performance.


  • New Face Slot Technology in 3-8 irons
  • Two slots located near the heel and toe of the clubface that provide uniform flexion across the face
  • Protects ball speed while generating more consistent distance on off-center hits
  • Improved Speed Pocket with ThruSlot Technology in 3-7 irons

  • Increases launch angle and ball speed on all shots
  • Advanced Face Design: Deep undercut and Inverted Cone Technology combine to promote maximum face speed
  • Improved sound and feel through advanced construction and multiple dampening systems
  • New Reax 90 steel shaft from True Temper helps to optimize ball flight for ultimate distance and performance

TaylorMade RSi 1 Irons Expert Review

  • Being an absolute equipment junkie, I was approached by GolfDiscount.com to write reviews and share my findings with you. Having been chosen to write a number of Taylormade product reviews for GolfWRX.com I felt that this is an excellent opportunity to put my knowledge to use.


The Takeaway

Much like the two other RSi Irons I tested, the RSi 1 incorporates the same Face-Slot Technology, Speed Pocket, and Thru-Slot Technology for improved mishits. An Advanced Face-Design producing a thin face with a deep undercut, combined with the Inverted Cone Technology promotes maximum face speed and consistency. This is the most forgiving version of the 3 different RSi offerings.

Who's It For?

I would have said in the past that Game Improvement irons are more for 18+ handicappers. Purists most likely will still walk by this section in the stores, but so be it. Now, pretty much any type of player can play this class of Game Improvement irons without hesitation, and there is one main reason. What held back the better players in previous years from using this class of iron was the hot spots, or jumpers as they’re called, which creates inconsistent distances from the same club number. The OEM’s have done a fabulous job correcting this issue with better technology in head and groove design.

Final Take

I’ve owned a set of these since Aug. 2014, played rounds with this set here and there. Looking down at the RSI 1s, I do not see much difference between them and my Burner 2.0 heads, other than the Face-Slots and a high-polished finish. Looks-wise, Taylormade has been very consistent with their Game Improvement irons over the years. However, they are also constantly pushing the limits to increase ball speed, launch angle, distance, and playability, and the RSI 1s are a great example of that. Personally, I liked both the TPs and 2s better than the 1s, even though I am used to the looks of the 1s. I found a much better overall feel from the TPs and 2s with similar results. There is a bit of a “click” to the RSI 1s that I did not experience with the other two. I prefer the softer finish of the other two RSi offerings compared to the high polished look of the RSI 1.
