Never saw anyone in club cricket score consistent runs with a jumbo.
They were just too heavy
A bit of a novelty bat
You'd see the odd big six hit with one, but I can't honestly remember anyone batting for long with one.
I'm a big fan of the thinking, would just prefer the spine to taper down more to the toe,and the spine to run more into the handle.
That's just me
Main thing is, if it picks up well, and it sounds like the 'pro' in the factory was very impressed
