I have the exact same issue Mirko. I smoothed over my biggest problems which is/are vowels by using word-linkage and crutch 4 mostly. But now I have problems with B, D, and St. I don’t know how it happened. So for B I drop the first letter, for St I drop the second letter, and D I assume I drop the first letter or just find a synonym. But I am also like you I use the crutches sometimes and not as often as I should be.
