I have broken 1 boom: North alu (2004)
Bended a few alu booms.
Now I have AMEX carbon boom 160-220. It is still in 1 piece after:
3000km = 1850 miles
Average overall speed is 25km/h
Hitting topspeed (yesterday) 77kmh = 42 knots
max 500m of 68kmh = 38 knots
max average 1 hour = 41kmh = 25 knots
AMEX boom is same as:
Prolimit
Gaastra
KA
and many more
The boom works for me

. However I dont crash very often had this year just a few 60kmh+ crashes
