I'm looking to swap out my low trs 2 trem on an ibanez I aquired and have NO clue which replacments wont require expensive routing and hassle...

I was looking at original floyd rose pro's,schaller floyds,lo-pro edges,edge pro's,but still not sure if they are accomodated.

Anyone experience swapping a low end rg trem(most likley a low trs 1 or 2)?Its a great neck-thru RG that if upgraded,could seriously wreck most US made RG's.You guys know the one...its the eh...the rgt42 I think?

Anyway yeah,if you know what would be a fitting replacment it would be much appreciated.
