Let me explain the terminology just a little bit. I'm a water guy - so these are descriptions for kites mainly designed for the water.
LEI - stands for leading edge inflatable. This covers Bow Kites and C Kites.
SLE - Supported Leading Edge. This is pretty similar to a bow kite. Its basically an LEI with a bridle. Waroos and Rhinos are a good example of these.
Hybrids - there are a ton of hybrids between C and Bow kites - too many to explain. But basically there are bow kites trying to get the advantages of C kites and C kites trying to get the advantages of bow kites.
Bow kites - Have a wide wind range, more power meter for meter, and have the awesome ability to depower. So when you are learning and you over correct you don't get chucked (yarded - launched) - you just let the bar out and the vast majority of the power is let out.
C Kites - traditional kite - shaped like a C - hence the name. These kites are known for their stability. However, they have less wind range than the bow kites and not as much depower. If you hear people talk about the shock factor when you first get the kite - C kites do have a shock factor - meaning if you over correct (which is normal when learning) you will probably get yarded - lauched down wind. (It can be fun though

- but sort of dangersous

)
OK - I agree that checking out kites is the absolute best thing - because kites are like cars - There is no one car for everyone, different people have different experiences with the same kite, and you need to figure out what your preference is.
If you are going to flying in light winds - 10 to 11 mph you are going to want to get a light wind specific kite. If you can - check out the 16M vegas. That would be a good size for someone your weight and the vegas has a lot of low end power - thats what a lot of guys use out here in the North West when kiting in light winds. Also, check out the Sling Shot machine - 17.5M would be a good size for you. SS quit making these in 06. These are light wind specific kites and you can find these pretty cheap. Complete for less than $300.
Keep in mind - bigger does not necessarily mean better. If you have a choice between a 16 and a 19 meter vegas - the 16 would probably work better - its going to turn much faster and have a better wind range. Someone your size really wouldn't need something so large.
So I will qualify my statements - these are my experiences only based on three years of water kiting. There are many, many great kites out there - check out as many as you possibly can.
By the way - both the vegas and the SS Machine are C kites. Just an FYI.
