I just ordered a 50mm… I do have relatively small hands so a 45 probably would be easier to grip (at least with my hands, but maybe not my legs), but it’s the only size I’ve used in the studio and I’ve heard it’ll be easier to size down in the future rather than size up from a 45 to a 50. All this talk about sizes is making me worry I got the wrong size. Am I still going to be alright with a 50? Haha
