Cui def only come in high and low, sit touch and responsive are softer than cui and come in low, med, high and extra high. I have extra high soft touch and mr Singh put them in, if you look at the product catalogues they will show the projections, the bigger the implant in cui the higher the projection but they would still come under high if they’re cui. The responsives are about £300 more and the soft touch £461. I’ll see if I can find the links for the catalogues for you, 525 cui are high profile but they do have very large projection, almost the same as the soft touch, but aren’t actually xhp if that makes sense x
