Hi there,
Need more info from you.
ie weight, experience (lessons) and where you plan to ride.
also read this kiteboarding 101 from
www.ikiteboarding.com/ There are some answers here for newbies
Rhino 2s are slow but have truck like pulling power. Also a 16 is NOT a beginners size.
A good start is a 12 metre generally and anything 2004-2005 Mid aspect
Board wise, not necessarily too long but wide for early planing
Underground FLX 142 for example is a good board to learn on as it is also a good board to progress on and becomes your light wind board in the future if you should progress enough to outgrow it.
Give us more info and we may be able to help you further
