Don't sweat the voice thing, you may hate it but others will never notice it. I have a horrible voice but still made a series of videos on YT. Nobody ever commented on my voice but did comment on how much they appreciated the videos. Go for it!

I'm interested in how the Kaizen battery hold down works and if you need to buy any extra parts to make it hold the battery in place reliably. Also, I was wondering if you had any problems with spur/pinion gears fitting. I'm running a 76/54 right now and it looks like they should fit no problems. Thanks!
