150mm/160mm 650b frames for tail riders?

i am looking for some real world experience of anyone riding 150 or 160mm travel 650b fs bike, who is over 6ft 3, and find they have a good frame fit, without putting a long stem on.

makes / models with a good real world reach, to begin pointing be in the right direction.

I am 6ft5 and currently ride a 140mm alloy norco sight with (150mm pikes on the front) which has a good reach even with a 50mm stem, but looking to upgrade, due to loosing a bit of faith with a norco over warranty issues, + feel I need a bit more travel.

any thought would be much appreciated.

Most manufactures seem to be able to spec the bikes well below the RRP cost of buying them separately in my experience. A frame only option makes sense if your transferring from one bike to another.
