Thanks for all the replies. I'm hoping the 14x5 or 14x4W will do the trick; if not, I'll be looking at three bladers.

Hobbsy, mine holds a steady 1960 with the 13x6 APC Sport. So idle is not a problem; I just want to slow the thing down a bit, but am concerned about loading the YS up and causing it to overheat.

Next, I'll start tweaking the regulator screw to keep the top end rich while preserving the idle.

I know; tread carefully there...<G>
