Shame you know **** all about golf then.
To the OP, definitely get clubs measured for you. American golf sell off the peg clubs that may be fine in the shop, but you need to get them set right for you. It's a bit like going to M&S for a suit, yes they are decent make, but they tend to be sizes that fit all, but are not quite enough for you.
I had a set of lynx irons, which I bought off the peg and yes they were decent and I wa shooting 16 to 20'handicapp. I had some lynx parralax irons specially made and fitted at lynx factory up in Surrey and I find then so much better and now shoot 8 to 11 handicap.
I think mid sussex GC also do a fitting service.
Give it a go.
Oh right. So golf is the only sport in the world where buying expensive kit is more important than loads of practice, coaching and training then.
Must have missed that bit when watching the pros talking about the years and years of constant practice and development of their game that they have to put in.
They must know **** all about golf and should just get a new set of clubs instead.
As others have said, there is no point buying bespoke kit when you've only been playing once or twice a year and are just stepping it up. Put the hours in and get your game to a level where you then know what kit you really need first. Otherwise you're just throwing money away as you don't really know what you need.
But you clearly know better.
