Well, I've been using Team Powers new Actinium V2(albeit in 17.5 form in my 1/12 scale car), & I've been impressed with it so far, good punch & strong at top end as well, with less timing advance than I'd need in my older motors(like my D4 Maxzilla, Schurrspeed V3 Sig. Edition, & Hobbywing V10 G2). Something else you might look at among the new gen. motors is Fantom's FR-1 V2 ( http://www.fantomracing.com/products.php?cat=21.5+Turn ), I think theirs are in stock & offer lots of options to set it up to your needs....
