I've not tried it yet but have also read that it makes the "feel" of bending strings rather different. Any comments on that ?
yeah, thats straight forward to understand. Its all to do with the excess string behind the bridge or nut.
if you have a really sharp downward angle there will be a lot of pressure at the bridge and nut. when you bend a string or even just fret a note it is much harder to affect the excess string - so you are mostlybending with the string between nut and bridge and the excess is affected less.... it feels stiffer to bend.
If you have less of a downward angle there is less pressure on the nut and bridge. When you bend the excess string will be stretched as well - so the extra tension is spread over a greater length of string and it feels easier, softer to bend.
Its important to note that there is no actual difference between the tension on a guitar with top wrapped or normal tailpiece - if there was the note would be different!! but its hard to describe the effect without using the T word so 'percieved tension' might be a better term.
This issue also comes into play when you look at headstock design - particularly comparing a righty fender head to a lefty one if anyone is trying to emulate jimi.
Thats how i understand it anyway - i am not claiming its 100% scientifically accurate or proven so take it all with a pinch of salt
