After I broke my Perceptor trying to get his arms in place, I started to think that most modern tf's whose transformation is hateful or at least irritating have arm problems getting into the altmode. So to prevent this from being a matter of pure perspective and my probable lack of small-motor skills and endless patience, I ask: is it the arms that usually are the problem? And why? My guess is that the arms are tough when they rely on the strength of the balljoints on the shoulders (RTS Jazz), don't tab in themselves but rely on a panel (Classics Sideswipe mold or Gen Kup), or seem like they will stress other parts of the mold (RTS Tracks/Gen WJ? -- I don't think all that twisting around bodes well for the future).
