O1CB irons

Hi Ryan
I have had your irons before and found them satisfactory.However the O1CB irons recently purchased with the tour lite shaft are by far the best I have had even against all the top brands ! Very pleased and custom built was an extra bonus

FedEx delays

Hi Ryan, I’d love to be in a position to give a review, but unfortunately I’m still waiting on delivery. Now been given two dates by FedEx, but looks like both are gonna be missed 🤷🏽‍♂️

Stunning irons, fraction of the cost, hole-in-one from Caley!

01CBs arrived yesterday, first hit today using indoor simulator and Trackman. Feel lovely to swing, incredible when caught sweetly, mishits (of which there are always plenty with me!) weren't too punishing, bad swings are still bad swings. Coming from P790s, these feel much more responsive when the strike is pure, but equally perhaps SLIGHTLY less forgiving when not. That being said, that's exactly why I opted for 01CBs instead of 01Ts as I WANTED that variation between the sets. 01CBs will be irons to really concentrate on and improve with. Cracking clubs.

Superb set of irons - was looking at getting a set of p770s but thought I'd give these a punt and so glad I did. Actually prefer the look of these and feel amazing.
