As the other fellas have alluded to, if you don't start in a drifter, you will be missing something in your flying career until you do and I have been telling those I know who have just kicked off flying a J160's and 230's.
For me, learning in drifter then moving across to a J160 was like going from a manual car to an auto when it came to take off and landing. The flaps etc on the Jab was just like having a few extra buttons on the stereo.
I can confirm that for me the J160 is a little more demanding than an LSA or J120 as it has a heavier and slower feel and less float etc when landing.
If it means anything, I recently went for a fly in a Tecnam P92 which I found to be a piece of cake. The instructor commented that she has found that people whop learnt in drifters and the like make far better pilots that people starting on heavier stuff.
Nothing the others haven't said, just my 2 cents.....
