helps you catch more waves
Yup, that's the main point: If you miss waves, it will destroy your learning curve.
Falling when not focused is one thing, but if you fall trying to catch a wave and being well-focused, I think the board is too hard and it is counter-productive.
Chief149, take your total weight in kg: you + board + paddle + wetsuit (a wet wetsuit can be a good 5kg). This gives you the "base level" buoyancy in liters.
Pros use generally ±5 liters off this base level.
Good SUPers would use +5 to +15 liters depending on conditions
Intermediates would use +15 to +25
Beginners should use more than +40
So, for 90kg, a base level would be ~105 liters in winter. 120 to 130 liters should be OK (depending on chop, board width, ...)
