... I used LR needles and that gives the mild slanted appearance and cleaner look to the stitching. 

I'm a total numpty when it comes to thing like this

What size needles would I buy for my Boss?

I picked up 346 thread and I am having problems with it. 
 

Both have been trouble but once I dial it in, the knot shows visibly in the middle in an ugly fashion. Tension on the top stitch  doesn't seem too great, so I assume it's the bottom?

What size of needle are you using with the V346 thread.

Here is a good reference chart for needle size versus thread size. ( https://www.tolindsewmach.com/thread-chart.html )

As a note you may have to go up a size depending on how thick and tough the leather is.

First question is what size of thread you want to use, then what do you want you stitch to look like and availability.

1) Thread sizing chart from Toledo Industrial Sewing Machines ( https://www.tolindsewmach.com/thread-chart.html )

2) Here is a quick look at the appearance of what the needle point will give. I grabbed these from the Techsew website ( https://www.techsew.com/en/blog/needle-buying-guide.html )

i) LR Point --- appears to be the more common point

ii) R Point

 

iii) S Point
