Martin if you havent worked out what it all means then i feel a little embarrassed to have to tell you...semi floating dont move as much as fully floating note how the fully has more bobbins or whatever you what to call em,allowing more movement?....your AP's may do the same kinda movement radial and axial but are not classed as fully floating touch a fully floater and you will see what i mean...lets just stick to AP's are floating to end it not semi not fully just floating.

...gotta go look for a fresh fish now
