Peak:
park/"our"freestyle, 19-26. that wil be when we are at our peak for strength agility, coordiation and such. plus we will still be powered by balls and testosterone (not sure if that is spelled right?). tho im not sayin older peeps cant tuck and huck.
big mountain, 23-29ish
aerials and moguls- 18-24
Limits:
as far as park, 32, since that would be the limit on what your knees can take
for big mountain, 45, cince ther is powder.
aerials and moguls, not past 30 since that is a major whooping on the knees past that.
