UST Recoil Parallel Iron Shafts

UST Recoil Parallel Iron Golf Shaft Review

RecoilParallelImageWhen the UST Recoil Iron shaft was first introduced I was enthralled by the concept of hoop deformation storing and then releasing energy. Hoop deformation was not part of the discussion in the club fitting organizations I belonged to. There was no publically documented procedure in the golf shaft business for measuring it. I was given some hints by another shaft company and set out on a long discovery process to measure it. Eventually it redefined how I calculated golf shaft EI by adding a correction for hoop deformation in the 3 point measuring process. This did not happen overnight. The journey lasted a little over a year, hoop deformation measurements are now an integral part of my understanding of the golf shaft. While I am forever grateful to UST Mamiya for bringing this to my attention, I did not find anything extraordinary about the hoop strength of the Recoil shafts. Generally it is a function of wall thickness, fiber orientation and layup strategy.

I recently obtained a limited range of UST Recoil shafts, including the Recoil 450, Recoil 460, Recoil 660, Recoil 670 and Recoil 680. Before we look at the numbers I realized in a conversation with a shaft company executive a few weeks ago that I was remiss in explaining my rating of shaft stiffness, EI Area. An article on the metric has been posted.. The concept was presented to me by Jeff Meyers who was the shaft guru at Titleist for about 20 years. By using area under the curve, each measurement of the shaft, from tip to butt is given equal weight in the stiffness rating. Jeff found it preferable over frequency to predict how golfers would report their impression of shaft stiffness. Frequency is heavily weighted toward the butt, overlooking the remainder of the shafts. As you read the charts on this site, your can compare overall stiffness of shafts by looking at the EI Area number in the tables.

Paderson Kinetixx Iron Shaft Review

When I asked Jason Horodezky for review samples I did not understand just how many shaft Paderson is making. Fortunately he did not send me one of each SKU as I requested, but he did send me the largest, heaviest box of samples I have ever received. At the speed I measure, it was at least 40 hours in the shop in between fitting, building and editing video from the PGA show. Iron shafts span 6 different profiles is various weights and flex’s. To see the range of shafts offer by Paderson, visit their website, Padersonshafts.com.

In addition to the catalog of shafts, there is an in depth discussion of their technology and manufacturing process which I am not going to repeat here with one exception. All but a few of Paderson’s shafts are filament wound. They are one of a very few companies that have this manufacturing technology. This video copied from their site illustrates the process.

Most carbon fiber shafts are made by rolling sheets of material over a mandrel. Paderson ‘spins’ a weave of carbon fiber ribbon over the mandrel. This gives them the unique ability to tension the fiber during the weaving process.

When you scroll through catalog of shafts on the Paderson site you will count 12 models in multiple flexes. I did not even put a dent in that array but measured enough to give you some insight into their designs.

Overall I see high quality shafts with atypical set stiffness designs. I will revisit this when I get a chance to compare the shafts to my current gamers.
