If you are of-roading on a bike then the smaller and tougher the better yes?
I don`t off-road but I do ride my Bandit 1200 pretty hard and I Longboard as well. I have a Vamo along with a couple of Ego batteries and the delivery devices are an AGA-T2 RBA, three Kanger Evods and loads of cartomisers.
I wouldn`t dream of taking the Vamo on the bikes! I wouldn`t think of taking any fluid delivery system (such as a clearo/clearo-tank or an RBA) on the bike. Great for steeping fluid if you need the vibrations but crap for the seals that hold the fluid in!
My unbeatable solution for an afternoon hooning around on the Bandit or the longboard is sweet and simple.
An Ego-c 900mah (even better if you can get a Twist) and a couple of Boge LR cartomisers.
Short and sweet, the Ego can be turned off so it dosn`t fire or waste battery in your leathers!
The cartomisers can be turned upside down and vibrated with no fear of leaking, you pull it out of your leathers and take a vape, switch it off and worry about the road/track and hitting the bend rather than your PV breaking in your pocket

It will last me an afternoons ride out and take some punishment as well.
Save the more complex and fragile stuff for when you get back to base
