Except for baseball (where a pure lefty would also bat left handed), you're almost entirely left handed (i.e. do the same as pure lefties and righties do).

Unless I'm misunderstanding the guitar bit, assume you mean fret with your right hand. If it's the other way around that's pretty cool, and I would think highly unusual, to fret with the hand that you don't write with.

Actually, now I'm totally confused, I write with my left and fret a guitar with my left, which might not be normal :)

I mistakenly wrote "throw with left hand" but it's the right hand as the others on that line.

As to guitar playing: Strumming with my right, holding the guitar to the left, like regular/right-handed guitar players. (Snowboarding, also regular, left foot in front).

Oh, ok, then we're the same :)

Left handed for the fine motor tasks (write, eat, ...) and right hand dominant for the rest (throw, bat, ...)

I never played (ice) hockey, but I believe pure lefties tend to shoot right handed, and vice versa for righties (i.e. with dominant hand on the top).

That's interesting, I'd never noticed that the majority of hockey shots are with the blade to the left. One-handed things like clubs, rackets, paddles, and swords, I like them in my right hand while most right-handed writers seem to prefer the right hand. Makes sense. So being a right-handed thrower with a dominant left hand would be the last thing where we haven't a good explanation.

Hendrix wrote with his right, but strummed with his left and fretted with his right. He also used a right handed guitar but turned it the other way and strung it for a left handed.

I just play a right-handed guitar 'upside-down'. While this makes it harder to finger many chords as I need to reach over the lower strings to reach the higher ones it makes it easier to just pick up any guitar I come across. I learnt it this way because of the way I learnt to play guitar, by picking up one of such and starting to play it - little did I know I did it 'wrong'.
