I have a bud from Louisiana thats been using this similar in his kswap 5spd tranny and every yr he upgrades the motor or anything to add more power the dam tranny is still holding up!!

We talking a bout a 600-750hp kswap tuned on BBG and running full slicks on the streets.
Thats why i dont get why many ppl have had bad experience with the Synchrotech syncros
Don't cryo treat your gears. That makes the gears harder. Which makes them more brittle not more resistant to breaking. You actually want to reduce hardness if you want to increase rigidity and strength. Sounds odd I know. I ran 550 hp on mine with a cryo treatment and the gears had visible cracks when I pulled them.

As I said before synchros aren't really the cause of our issues, it's the engagement teeth on either the hub or the gear itself. Some people have fine results with the after market synchros, but it's honestly a waste of money.
