Vigier Guitars

Hello.

I have a Vigier Excalibur Supra 7 and one of the flexretainers has slipped away and the vigier support team said on facebook that i can take a ball end of  an high e string and put it there.

Someone actually did that and can film a video for me or else write instructions page

And also.

Someone installed there a tremol-no and made it dive only mode, and i want to make it to function similarly to a petrucci model, 

but how much its reducing the sustain of the guitar? does it dropped dramatically? Because it's extremley important to me.

And also, corrently every time i dive bomb it's not staying in tune, how to keep stablity?
