Flatlander, I believe you'll need a heck of a lot more weight up front than that with the 350's.
Heck, I bet you could bump up your point weight on the 250's and get where you need to be.
That's stiff for a 28" arrow out of a 54# bow...just food for thought.
I think what most guys don't realize it that for "most" hogs, any regular ol' deer hunting arrow will work just fine.
Young boars and most any sow will be pretty easy to shoot thru if hit where they're supposed to be hit.
So in 90% of hog hunting situations, you can get away with "normal" equipment.
BUT....
If you ever get a chance at a big, tough, mature boar hog, you'll appreciate every pound of bow weight, and every grain of arrow you're shooting!
Hog hunting by nature is a very up close and personal hunt. So a good, heavy arrow is always best....just in case a big ol' boar hog shows up.....
