Wilson Staff Di7 Irons

After spending the last few weeks fighting with my Titleist AC-108, I decided that they weren't the clubs for me, which is the unfortunate side of buying online. They may be cheap, but if they aren't suited to you and you haven't had a chance to try them before buying, then you've just wasted however much money you've spent on them.
My problem with these clubs were that the heads were just far too small, or at least in my mind they were and I couldn't look past it. It was affecting my swing constantly and whenever it came to using a longer iron that didn't have a high degree of loft, I was screwed. Topping, slicing, shanking, you name it, I was doing it.
I ended up having a look around and read up about game improvement irons, which have more loft and a cavity back, which to my understanding help you get the ball higher and further.
I went into my local golf shop in Aberdeen and when browsing the shelves, noticed a second hand pair of Wilson Di7 irons, consisting of 3-SW for only £100. Now these things were in pristine condition and looked as if they had never even seen a golf ball, let alone hit one.
I asked the guy in the shop if they could put them to the side for me, whilst I decided what to do and researched them a bit more. They kindly obliged and off I went to begin getting as much information about the clubs as I could, as well as pricing them up elsewhere to see if I was really getting a bargain or not.
From looking around on sites such as eBay, I soon found that a set of these irons were going for roughly around £140-£200 and that was only for a 4-PW, so to get the extra couple of clubs at even less than that seemed almost too good to be true and my assumption was that the irons must not be too great, but even reviews were saying that they were a dream to hit and definitely helped improve other beginners game.
I had learned my lesson of not being able to try them from buying online, so when I went into the store I asked if I could give them a hit before buying them and they were more than happy to let me do so.
Hitting them felt great and I was managing to get the ball in the air on the simulator. I decided to go ahead and buy them and have definitely felt that my iron shots have improved. They may not be perfect, but at least I'm actually hitting the ball a bit more consistently on my longer irons now.
I'll have to report back once I've used them for a longer period of time, but at least for now, it's looking promising.
