I am still fairly new, but the HG's I've done are apparently newer and better designed internally. I wasn't prepared for the screws, and then the crazy tube construction. After completion, his left arm also has trouble sustaining the shield poses. The end model is still awesome and not to be missed, just maybe look for a newer MG for your first foray into this tier.
