IMLE (in my limited experience) you have to be careful with a swap like this. Most likely your current crank and spindle t are not JIS so you will have an interface issue that you need to decide if you are comfortable with. Also the spindle is most likely asymmetrical so you might end up with different clearances and may need a different spindle length to get a good chainline.

Spa Cycles, Harrowgate England. I've ordered from them in the past, shipping price and times quite reasonable. Stronglight Zircal 86bcd rings starting at £17.00

Lass year, when I was looking to replace the rings on my worn BIS crank, I swear they were all over the place- just not the drilled BIS rings... so I wasn't interested... now I look and I see them pretty much nowhere. Maybe I was looking for the wrong ones,

Some of them are, anyway. Sakae Ringyo made a number of different cranks under the "Apex" moniker. There is the 86mm BCD model you mention, and also a 118mm BCD model, and a 144mm BCD model.
I think "Apex" was used to indicate a forged crank, while "Custom" was used to indicate a cast (aka "melt forged") crank, regardless of the BCD used. There was an 86mm BCD "Custom" crank as well.

And speaking of cranks- I'm hoping to get to the VSP/Trek 720 tonight when I get home!

So with my 6 speed freewheel and rear mech, could I use a (e.g.) 9/10 speed double chainset if I was to get a narrower 9/10 speed chain?
