Triple X Nitro size, or Phase 5 Carbon X, or IS sweet spot??

Ok, I'll try again, looking for a new board for a CC230 vdrive, will have add on ballast, approx. 2500# total.

Boards I'm considering;

IS Sweet Spot Pro
Triple X Nitro-size?
Phase 5 Colt
Phase 5 Carbon X

I'm about 175, wife 120, we both were riding an IS Red Tide behind our DD previously.

I have surfed the Grindwater Ginsu and Makua (?), IS Blue, and some other comp molded boards.

thanks
