Hi omarissag, I learned on Fanatic ha 2000 which is very stable, lifts at low speed and great for learning. It was really good at the beginning and helped me to learn gybes and do foot switches. Now, I don't use it any more and for light wind I am on glide v1 1305. The main difference is the amount of glide the foil has (it is thinner and has much higher aspect ratio). It makes it much easier going through lulls compared to ha 2000; it is also a little faster than HA 200. At the same time it is a bit less stable (especially the pitch) and would be somewhat more difficult to learn on. Glide 1595 would be very comparable to 1305 with even lower stall speed.
If you are buying to learn 2000 would a be a little easier but you would outgrow it faster.
I am a heavy guy with 120kgs and had both wings.
I learned wwith the Lift 2400 and HA2000 and later bought the Glides 1305, 1595 as well.
I got rid of the 1595 very quickly. It only rides well in a straight line and does not like to go into gybes.
As well it felt very slow and draggy. Prefered the HA2000 in every ways and sold the Glide 1595.
Went for the Free 2000 instead and prefered the Free 2000 over the HA 2000
