8'6 Fin Recommendations..?

A board I ordered almost a couple of months ago is apparently finally en route.

8’6 x 22 1/4 x 2.9 squashtail “longboard”, light single to double, 2+1, shortboard type rails, moderate rocker, EPS so should be light…

Haven’t been on a longer board in some years (couple of compressed discs are less problematic when surfing mid-length boards in the 7’6 to 8’0 range), so need to pick up some fins and start experimenting. As the front boxes are Future, picked up some SB1 sidebites, and would welcome sugestions on primary fins to throw into the mix as I try and dial this board in.

Board will be used in walled up beachbreak up to the head high range, at which time I’ll jump on a shorter and racier board…

I was riding a 9’1" with a 2+1 set up. Similar width and thickness, just a bit longer. Went from an 8" centre fin to a 7" inch centre fin. Board felt just as fast and was easier to turn.

just a follow-up to my original query - thinking of Yater 6.5 Classic, Rusty 6.25 Flex, or 7" ames cut-away - any feedback on those fins or suggested others appreciated…

7" True ames cutaway, fast loose, had that on an hobie performance noserider and it worked really well especially when the waves were under head high.
