So I put this into my Callaway Epic Flash SZ a few months ago, and obviously haven't had a chance to hit it. Dumina say it should have a swing weight of D0, but that does seem very light. It is a light shaft anyway, (45g?), and at D0 I am not convinced. I have mine weighted at D2.

So today, at the golf club.

I had a warm up in an outdoor net, and it was a bit odd to swing, and every drive came off the bottom edge. For anyone not familiar with Autoflex, the shaft is extremely bendy, (think ladies senior flex, and then a bit bendier).

Swap to the indoor simulator. Still interesting to swing, but after a few more goes, the good ones started to arrive. It definitely added 3 mph to my swing speed, and a good few yards to my drives. It also was very easy to hit a nice draw shape. A few were a bit high spinning, but in no trouble. Most were very tidy.

To the course.

3w off the first, into a fir tree, never to be seen again. Might as well have hit driver.

Driver off the second, a repeat of the 3w off the first but found it OK. 3rd hole, nailed it. Very nice shape and distance. 5th, toe poke (this set the tone really, I just kept on toeing it). Didn't really put a decent swing on it until 14, when I crushed it, and then promptly went back to a toey roof for the remaining holes.
Oh, 10 was OK, but I set up with the ball a bit too far forward, ignored it, and pulled it way left. It was middled though, and was only saved by the trees.

So?

I think my swing is very rusty, and I think first time out was a bit nervy, Proddy and steery. When it goes, it does go. If I had played with my Evenflow Stiff, would I have played better? Not with that swing.
Happy with it? It will take some more outings, as I think it will take a bit of getting used to, but yes, I think so.

Worth the money? Depends how much you have, and what you want to spend it on.

No. I think it sounded pretty solid on a decent hit. I was quite happy with the noise.
I like it as well, feels firm but soft, this sounds like a shaft working in the right range. But it’s the control that it gives compared to other shafts that give the noise and feeling that makes it stand out

Really happy with my SF505, it’s not the distance gain, which isn’t huge but it’s the fairways hit. I hit more fairways than normal, I feel confident to play on narrow holes, where I would normally step down to a 5 wood. Fingers crossed this carries on, I need to just get a little more launch angle, but that’s just getting the weight on the back. The shape is also subtle fade or draw depending on what you call for. The big thing is a slow takeaway and smooth transition into the downswing, if you don’t have that the shaft will wobble - but it does a great job of mitigating this and restricts the miss very well

Thank you for the review. Is anyone in the UK stocking it officially? Did you have a fitting for it before buying?

There are fitters with it Precision Golf near London, and the guy who supplied me was off eBay but he was a fitter and builder - Tour Issue Golf was his website so have a look.

Not overly familiar with the auto flex? Is this the pink and black shaft adam scott has been using?

Is he using a softer than senior flex shaft. Seems a bit odd.

No the shafts are in swing speeds ranges so probably in an SF505XX.
I am using an SF505. Have a google, lots are trying some positive stuff some negative- it is controversial because of the cost. But in the end it’s no dearer than buying the latest driver with an up charge shaft. What is interesting is watching the other manufacturers trying to emulate it.
I got one out of sheer curiosity and I had some budget from my eBay activities.. I was going to buy a new driver but thought I would give this a go and if it didn’t work I would cut my losses. But I really looked into this and what made it work, who was having success with it and what were their settings.
So if your interested PM me and I will give you the full specs and findings.
