The Litewave 148 is a good all around board, durable and easy to ride..
I have ridden the 148/158/169 and found that the 158/169 were great for lite wind and the 148 isnt all that great on the low end..
I am 70kgs so the 148 may suit you just fine.. If you are going to ride in moderate to heavy winds(whatever you are gonna kite in most of the time) I'd opt for the 148.. Litewind you are gonna want a bigger board..
Watch those edges cause they are pretty damn sharp.
As for your kites I am only familiar with the Wipika, and IMO dont think its a well suited kite for a beginner..
Look into the Slingshot Fuel if you want a tough ass kite that will handle abuse better than anything out there IMO... Mine has crashed into 2 roof's and still she flies straight and strong...The 2002 Slingshot Fuels are great kites and can be picked up at a reasonable price..
If you want to get your gear from a reputable source that will stand behind what they sell drop me a line.. They stock SS and Litewave boards.
Good luck and by the way
