JW and JS are a bit too small. Or the JS are but the rake looks good. JW I forget but I crossed those off the list. I have the Khloes and I used them once and was done."Beveled" refers to the leading edge, if a quad rear is 50/50 or 80/20 beveled side fins feel like 95/5. The MF, my go to, are like that too. Couldn't really tell a difference between them and the DHDs by the way.
Did you check out the fcs fin data page yet? JW and JS look like they might fit your bill.
Much like chase and bird my experience with futures has been a PITA, there always seems to be some sort of issue with fitting. I also don't like that the location of the screw requires fins with bigger base to have a cutaway design.
Really wish fcs would calm down with the graphics a bit though and offer some full fiberglass options.
