Ehem!
The D11 should be the starting point, it is the safest JUG for someone who wants to do more than B&Z and has interest in learning how to JUGgle.
The M would be next step as it will teach you energy management (not that it holds E well) but it has the motor to recover lost E quicker than the others and it has the legs to escape trouble if need be. I always thought the M to be a hotrod, and was my choice if I knew I was going against "good" k4 fliers. It is not in the same league as the k4 but it can be a very nasty surprise for K4 drivers who take it for granted.
D25 and D40, well IMHO these 2 rides are the worst JUGS, I think the D40 edges out the D25 mainly cause the D40 retains E better (some would disagree) but it is what I've found. So if you get good in the D25, The other JUGS will come easier.
The "N", just thinking about the "N" makes me want to return!!

It is the little things that matter in the closest of contests. 200 mph stock cars will benefit greatly by getting .005 mph increase with tire pressure changes over 100 miles, the N JUG is very much like this to me. The N has the most "little things" to draw from, they are subtle but put together they can be the difference between gloating and sitting in the tower

The bigger, clipped wings allow it to float very well, with rudder assist the roll rate is superb. Rudder, lets just say it IMO is second only to the corsair rudder. The energy retention of the "N"aughty Lady is the best of all JUGS, probably from the added weight which I will add does not unbalance the N, in fact I would say the N is the most balanced and dreamy JUG in the game!!
Many think the M is the best JUG, but I always found it to be a very rigid and inflexible ride, the N offers the most options during a fight. The M always seemed to advertise its "game" in other words, most everyone knows what to expect from the M, the only difference being how well the driver does those "expected things". The N comes with a "bag of tricks"

But it requires more experience to get the most out of the N.
Years ago YUCCA flew the N and was possibly the best JUG driver at the time, he returned about 5 years ago and I was inspired to take up the JUG and try to figure out why in the hell he always flew it the way he did. Low, slow, ganged and molested. YUCCA volunteered some advice to me one day, 5 simple words that stuck!! " RUDDER RUDDER AND DON"T MISS " <-- the best advice for an aspiring JUGgler.

He returned again about 2-3 years ago, we fought each other and flew together at times which was a massacre unless Kappa and Grizz were around

but it was great fun, sadly I think that was his last hurrah!
Lastly how to tell if you are getting any good in the JUGS. Measure yourself against "GOOD" corsair drivers. The corsair does everything better than the JUG but they are similar. IF you can push a "GOOD" corsair driver to pull out all the stops and work hard at killing you, then you have arrived. Do not expect to win many encounters against equally skilled corsair drivers as the corsair is just plainly better, but they are a good measurement of your improvement!
Me in a corsair will PWN me in a JUG, but me in a JUG is a handfull indeed!!

Go forth and JUGgle
good luck
