looking for opinions on them

 

If I had an FXST like yours, that's the seat I'd put on.

 

i've got one on my night train. i love mustang seats. this is the 2nd mustang seat i've had (had one on my vstar before my harley). i broke a bracket on my vstars seat and called up mustang and they sent me a new bracket free of charge and i got it really fast. as far as the regal duke i can ride for hours and my butt is fine. and my wife doesn't mind it at all either. i've been really please and if i ever get a new bike it wil have a mustang seat on it.
