Best piston for street/strip 340?

I have been trying to keep up with a couple related threads,
340 Stroker Build Need LOTS of Advice
and
A few questions about stroker small blocks
Since I started my project I was convinced I wanted a stroker esp since a buddy of mine gives me loads of **** about just having a small block. I remind him that at least I have a classic car.
Anyway, life changes are having me think about scaling back cost to finish, & rethinking stock stroke option, but getting most bang for buck without being cheap about it.
I was interested in MRLs last build,-stock stroke, but longer rod-shorter piston. I now think it might be prudent just to keep as stock as possible, but use "newer thoughts & materials" for my gains. Lighter pistons, less friction, etc. In my reading I remember seeing Total Seal Gapless rings a few years back. The gains weren't huge, but it seemed like sound logic, & not a huge cost. Lighter pistons, less friction don't offer huge gains on their own either, but combining as many small gains as possible will add up.
Does anybody have experience and/or recommendations?
