I completely agree that the G70's VK sim is crippled in comparison to the real thing, and also that probably the best single manual B3 sim is either the XK-1, or even better (now that Ian reports the Leslie from the XK-1 has been ported), the XK-3.

BUT.... I realize this is the General ARRANGER forum, and, as such realize that most of us are primarily interested in playing with arrangers, and from the constant whining about weight, generally accept that most of us are looking to gig with the minimal setup possible. So, although the G70 lacks a little in the B3 comparison department, I feel that a) of all the arrangers, it's B3 sim is still the best (but could definitely be improved), b) the keyboard feel and size, tied to what I feel is still the best grand piano sound of ANY (non-software) arranger, is the most versatile for ANY of the included sounds with the LEAST compromise in action (and can always trigger a Roland, Nord or Hammond clone rack for more authenticity if needed).

Most of us probably gig with ONE keyboard. In fact, most of the posts here involve the acceptance of at least SOME compromise to achieve this. If you ARE looking to play piano AND organ as main sounds, whether with arranger section on or not (I do most of my full band gigging and a bit of studio with just the G70), I can testify that the G70 action (whether you like the OS, sounds, styles or not) is by FAR the best action to be able to use your well-honed traditional techniques on, with the least compromise across the board.

OF COURSE you can find specialist keyboards that push the authenticity to the limit. But if you chose the arranger route, you'll have to accept that just ONE keyboard is going to have to cover ALL the bases. Rather than bring an arranger, a B3 clone AND an 88 woody to every gig, I simply find the one action of the G70 covers it all...
