Check these out.
Real composite light adjustable paddles.
A range in the EXP-stretch7.5" of 70" to 82"
The EXP-3 piece 65" to 80"
95% of adjustable paddles I have seen or used have been crappola.
These are the first adjustables I've seen that are really good.
As with any Hobie product they are top notch and the price is a pleasant
surprise
