I’ve done it plenty of times, typically in the 4/5 spot, Be it a 5i and 5h because hybrids are typically longer distance than their iron counterparts, or even two 4i or 5i when one is a players cb and the other a GI/SGI used as a utility.
Numbers on the sole as well as the loft numbers of the clubs don’t matter, distance gaps matter
Not currently but in the past I had a 3-iron (steel shaft, 21 degrees, 39") and a 3-hybrid (graphite shaft, 19 degrees, 40") in the bag at the same time. They had totally different ballflights and the 3-hybrid was about 12-15 yards longer.
I knew a guy, years ago, who had a set of irons up through the PW and then two "sand wedges". I asked him what lofts and he said, "This one is 57 and the other one was 56 but I had it bent to 57".
Dude had magical touch from 50 yards in so the wedge obviously did their jobs. Around the practice green I watched him for 20 minutes hitting pitch shots over a bunker with whichever it was of the 57-degree sand wedges. It was hypnotic, he'd hit one shot after another that would roll up and nestle next to the previous ball. After half a dozen shots, he'd move to a different distance and make another beautiful little cluster on another part of the green.
He told me his key to a good short game was soft hands, steady tempo and repetition. Lots and lots of repetition. Of course he'd been playing golf since he was three years old which I think helped a lot.
I don't but I know a guy who carries 3 putters. He has one that is a triangle and is about 25 inches and is for 4 foot and in. He never misses...and I mean never. Side straddle and just jams it. Then he has two other putters. One for 4 foot to about 20... and then one for lagging. He is a notorious player in the GAP. Golf Assoc Philly. He has won many events and championships.
Currently went back to my OLD Hogan Edge Ft. Worth's (for confidence reasons- they just feel right) and kept the 3I (21*), also have the Hogan Ft. Worth Hi 3 @ 18*. That gets used more as a driving Iron.
