3.90 vs 4.10

well the rear end poped and i had 4.10's in it but im not sure if i should get them again or if i should get 3.90. The acceleration with the 4.10 is amazing but to many people wanna do 50mph rolls and im tacken around 4700-4900 rpms and when i have to shift around 6100
my bolt ons are longtubes,fast90/90, slp cold air intake kit, UDP,deleted egr and air, deleted cats, gto spec 2 tranny oz700 clutch, xpipe flowmaster 10 series true duels. let me know what you guys think
