I got my RM Prosthetic 4.5" last mouth.  However, I found a differently in playing sex.  I think its because of the weight.  The prosthetic is heavy than what I expected.  So now I am thinking to buy another one.  I am thinking in FTM Prosthetic Dual Mid Size or RM FTM Prosthetic 6".  Can someone give me some idea?  Thanks!

I have an older version FTM prosthetic dual, its detail and feel can not compete with RM

If you do a search on youtube there is a comparison.
