What do you suggest for the best feeling pedal assist?

Can't you use a throttle for take-off?

I could, if I had one. But so far, I'm enjoying not having a throttle (at least 95% of the time).

After four years on various electric bike forums, I postulate a theory: If you like dressing up in lycra, you will probably prefer a torque multiplication system with a torque sensor. If you prefer to cycle in normal clothes, you'll probably prefer a pedal speed sensor with a decent multi-level PAS system.

Some systems use the torque sensor only to determine that you're pedalling, but the controller still works on speed control. Some systems combine torque speed and cadence sensors in an attempt to give ideal power. IMHO they all have advantages and disadvantages.

The only PAS systems I'd definitely avoid are single level ones with a cadence sensor, higher powered ones with a three-speed switch, and the most diabolical of all: those that give more power the faster you pedal.

Exellent post.

If you use speed instead of current regulation, is the S06S noticeably better than the KU65 with its 3 speeds? I mean wrt to the riding experience, disregarding the extra info re speed, distance etc.

BionX motors can be bought quite cheap over here at ebay.

Any links? I've broken the axle on a 1st gen BionX wheel and would like to have a spare but I never see them cheap.

Yes. In terms of normal performance figures, not a lot of difference, but smoother, and the five levels of PAS give more options for increasing range. Plus you get a nice LCD for speed/distance display and adjusting speed limits, etc. Basically, things have moved on controllerwise. The S06S is modern and full of features. The KU65 was good in its day.
