There was a pretty comprehensive thread on this very forum detailing neck shape and dimensions through various eras of tokai history.
It's still around somewhere but unfortunately a lot of the info came from a forum member who has since left us and deleted all his posts when he did so.
However, it is well known that Tokai's Gibson replicas have almost always had a 50's carve, which is quite chunky by modern standards. It's slightly thinner and has a more comfy shape (IMO) than the 50's carve on the Gibson LP Standards. My advice would be to track down a Love Rock/SG and try them out to see how you get on with them, and don't discount them immediately because you think they'll be too fat. There's too much of that kind of thing going on these days thanks to the internet; people getting a spec into their head and making decisions while never getting their hands on the guitar in question.
I don't have huge hands and my tokai has a very hand-filling '58 shape - I love it. I knew it was perfect the moment I wrapped my hand around it. It makes chords so much easier and greatly reduces finger/thumb strain when playing the high frets.
