Yeah, I think a proper wide angle is very useful for filming, and you can get them that barely distorts round the edges. Krisboats has a good wide-angle.
Pfft. If I sidehop to the other side, it feels horrible. If you want to be at sidehops, then learn it to both sides, if you just want to be able to sidehop somewhat, it doesn't matter.
What side you do it doesn't matter. If you get your front wheel on, lean into it and pivot the back wheel on, job done! What does 'Bol Maaaaaaaing' mean anyway?
If you have QR wheels, or even if not, and you also undo the stem bolts, a bike will fold pretty flat so you could put it a few places - under the bed, in the wardrobe, in the bathroom if you have one...
