help with board purchase,thanks

Hello,

i hope you can help me out, this boards i have locally and i need to chose asap.
Last board i had was 140 marek 2017, but it broke after only one season...!

Murray 2019
Parks 2019
One/Timebomb
Slingshot Nomad 2019
Slingshot PiLL
Riot Bio 2019

I am fairly intermediate rider ( i think), stable cruising, w2w, grabs,180, backroll (although i am still trying to master it) and this year i would like to try air ralley and maybe tantrum...Riding ONLY behind the boat, 2002 Malibu VLX with a bit improved stock ballast.
I am 40 years old, 178 cm and 84 kg.
Also, i saw a lot of people are leaning toward longer board, so i am not sure , shall i go from 140 to 144, or maybe even 150...? I am scared that 150 will be way harder for inverts, because i yet need to learn it ...
Thanks!
