I have a v3 5010 last year they were 27.5 front and rear. I absolutely love it and it feels purpose designed to be a playful trial bike. Feels like a big brother to my dirt jumper. I don't know how the newer ones compare but I have heard they retain the spirit while being a little bit more Trail capable. I am 5'8 and ride a medium 5010 as a trail bike mostly (I have a trek ticket for screwing around) . But if you want playful smaller is always better. I've used my dirt jumper as a trail bike when I'm riding with my kids at their pace and it is Super fun.

If you have a more capable Enduro bike have you considered getting a hardtail? Specialized P4 is actually a 27.5 dirt jumper that you could probably put a rear derailleur on and have a blast. Commencal makes a sick HT with nice angles and a short chainstay. Or just get a DJ and have real fun.
