Ibanez Rg2228 Gk Vs Ibanez Rgir 27

Hi guys! I'm in a bit of a dilemma and would really appreciate some professional advice on this. Basically I really want a 7 string, i recently got into Periphery and I love their stuff and want to make my own songs that are that heavy.

Problem is that in the city I live in (Rotterdam, The Netherlands) has one good store and that store only has these 2 guitars: Ibanez RG2228 GK and Ibanez RGIR 27.

The RG2228 I've been told has better quality wood in both neck and body, however it is an 8 string and I really don't like the sound of the 8th string, way too low for my taste. In addition, the neck is quite uncomfortable because of the 8th string.

The RGIR 27 has a very comfortable neck, even with the extra string. They both have EMG's in them so the pups are good in both. However, the build quality is supposed to be significantly worse. I don't really know as I don't notice these things, but I suspect the shop keepers are telling me this to get the more expensive one, the 8 string RG2228 GK.

As a final note, the RGIR is 700 euros and the RG2228 is 1400, so double the price.

I really appreciate any opinions you guys have on this. Thanks a lot!
