Yeah, the RR Leather/RR Cap/Henchman bow does come close, but has 3 h/s vs 9 for the Customized Recurve. How much difference that +6 h/s makes is debatable, when you factor in the higher armor using the Henchie bow.

First few runs with RR setup, I had to use a lot of pots, which was to be expected. Using the +2 dodge/8 armor ring boosted armor to 91 and seemed to help a little and seeing a LOT of orange crit hits made me happy in the pants I certainly couldn't write numbers down in action, but seeing ridiculous amounts of crit hits during boss fights was the bomb.

Only way to truly test would be to do something like you did in Close Encounters with the Sent/Void/Megablaster set comparison. Would be hard to solo the Sewers even with a tank pot due to the dense hard-hitting mobs, fire grates, and limited space.
