40 stamina monster chopper

What should i focus on? Can laboon/vivi beat monster chopper?

I have 
Princess vivi
Tashigi
Kuro
Smoker
Diable jamble
Valentine
Horn point
Mihawk
Gp usopp
Alvida
Towel nami
Vista
And more

Kinda looking at making a good lion song friend vivi team if laboon doesnt work. Any suggestions?

You really only have two choices, vivi/laboon or vivi/lion zoro. Suggest vivi/lion zoro because you have no hp limit and can use anyone you want and therefore is much faster. Since you have two turns before chopper attacks, you will be able to fully heal your hp unlike 40 stam mihawk

Just to make this clear for lion zoro vivi team, your vivi must be lvl 73 at the least (you will take 2014 or so from chopper when he does his hit). After that I would suggest you put diable jambe sanji on your team as stage 4 can be a pain if you don't have enough high combo units and then just some more qck hitters. Maaaaybe do mihawk but I don't see you getting his special off right when you start stage 5 so his special is much worse if you don't do it when chopper is full hp.
