Hi Steve,

The iRule looks good. Probably a problem within the 

snip
part or recent changes are not getting active (aka. open new TCP connections after changing the iRule).

Another problem could be, that you're trying to select a specific member for the given pool and that active persist entries are still getting prefered. Last but not least make sure to assign a OneConnect Profile if you're trying to switch between members of the same pool.

How about using a dedicated pool with just the 1.2.3.4 as member? This would eleminate many side effects...

Cheers, Kai
