FMJ spindles > POLL

I run them. You couldn't possibly have any issues with them that you wouldn't have had with 73+ A body spindles.

This is the article that anyone questioning this swap needs to read...

Actual geometry analysis of actual spindles showing camber gain, toe gain, etc. Short version?

"The Final Outcome
Overall, using the B-spindle will result in geometry changes that are unnoticeable with all but the most aggressive drivers running against a stopwatch. Even at that, there's a good argument that the increased camber gain will have a positive impact on cornering while the increased toe-in through extension will go undetected."

Further argument for those of us running wider tires- the camber gain will be more noticeable with wider tires, while the toe in effect will be decreased. Ultimately, I think this makes the F/M/J spindles a BETTER choice from a geometry standpoint for the Pro-Touring or road race/autocross crowd that run wider and softer compound tires.
