IER-Hop vs. R-Hop

I was hoping to upgrade my HK417 with a IER-Hop, however the local gundoc cannot source the IER-Hop parts kit for several months, but can source an R-Hop. Can anyone comment if the performance improvement with the IER-Hop is worth waiting for, or if the the difference is negligible enough to install a regular R-Hop?
