The retainer is only usefull if the headstock is not tilted so I've always wondered why Jems/RGs have it.
It's a must on JSs and Strats but totally moot on Jems/RGs.
In fact I'd be more worried about the friction you'd get on the locking nut when bending strings as the contact area is bigger and it was never designed to facilitate string slip so hard playing will push your guitar out of tune.
I've blocked the trem on my main guitar but still lock the nut as well.
Just take the
retaining bar off - it won't have any effect on an RG

P.S. I had a look at some of my guitars last night and it looks like the slope on the locking nut on Jems is really steep and even with the tilted headstock the strings are not lying flat on the locking nut if the retainer bar is removed.
That would mean that without the retainer bar locking the nut will push the strings quite a bit sharp so having it there is a good idea but if you are not going to use the pressure pads at all then the retainer bar can be removed.
