I understand all too well.
I had to "tweak" the Bespin mounts quite a bit, but they´re still not quite right (the lower edge is rounded instead of a clean 90° angle).
The Hoth mount was used as it is, but with my real TD124 disc instead of the repro one PLUS I used my existing flashhider!!! The BD just did not look right.
BTW: I´ll be having a Hoth DL44 kit up FS soon :cool
Agreed... That's why I made my own ESB mount for my live fire Luke. My hoth also will have a non BD flash hider... that one just seems too long and big.
