Interesting that for me 633 feels more rigid in 111 mast than on 91 mast. On 91 i feel more vibration. But of course on 111 you need more drag start to go, not so lively and other foots possition stance.
this is true, in fact I found the 91mast just too soft using the 633, made worse by my 95kg weight, getting up to speed was frustrated by the instability caused by this combination, in turbulent water it felt like the mast was faulty, after asking around the guys who had the 91mast and had changed it for the 101 said they also had the same experience using the 91, something none of us complained about when learning on smaller wings before larger wings became normal, even the 590 gave me the wobbles as I tried to push for speed, the 101 gave me a solid feel, I had the 111 mast but never needed it. so sold it.
Just to add to your thoughts about your son wanting to upgrade his kit,
this reminds me very much of the father and son I met at flag beach early last year, Italians, dad around 50years old son around 18yrs old, both away for a week foiling at flag.
both on Moses kit, son was maybe 35kg lighter than dad, both good foilers but dad was more advanced and liked racing at club level back home,
this is the funny thing about their choice of wings, dad was the bank of dad, son was a student but dad bought him the kit he wanted, 70% of the time Dad used a 633 wing and son used/owned the 683,(679)
but on the more windy days dad borrowed sons 683 to practice his race tacks and speed upwind, he loved chasing me around to see who could go faster, he was faster than me on that wing and he loved it, but he left his son using his 633 for the day, and back on shore his son was always in a strop about dad pinching his wing yet again, his dad explained to me he loves the 683 for club racing as its a better wing for race style tacks, as he falls in more using the 633 when tacking, and as he explained, the less you fall in at club level the more chance of being at the front, he was amused at the mood
his son displayed when he was forced to use dads wing, uncool!!
