Anyone use #415 or #554 thread in machine

Looking to see if anyone sews with this heavy thread in making hard use gear or is the #346  as heavy as you go

I use 346 in 95% of the stuff you can see on my website:  belts, holsters, mag carriers, phone carriers, etc.  I have 415, . . . and I cannot swear that something on my site may not be done in 415.

If I need anything smaller, . . . I use carpet thread and a plastic, Walmart, sewing machine.

What little saddle stuff I do, . . . again, . . . 346.  Part of that is that my Tippmann Boss likes it best, . . . and I've learned how to use it, . . . 

May God bless,

Only every once in awhile do I use 415, usually when someone brings a tow strap in to repair.  I use 346 on saddle skirts and most work harness and heavy using tack. Lighter harness (carriage-type, pony, etc,)  finer tack and show tack gets 277. Part of the reason I like to stay with a lighter thread is I don't like leaving a great big hole that the larger needles make.  Only occasionally I might use 415 on work harness tugs, but normally a 346 on them too.  I sew nearly all my tugs with a knife in my machine, laying the thread in a channel, so it's not likely to wear through until the back layer of leather is worn pretty bad. The 346 lays in the channel nicer than the 415.
