I held an M11 in my hands last Friday. It is big, it is cool looking, and I didn't like the feel of it at all. The wheel feels in a completely different spot which it is a little bit. The main thing I found though is the plate behind the wheel I kept hitting my fingers on while turning the wheel.
You can definitely feel the weight difference since this thing is a little top heavy, but I really don't think it would affect you in a main or nothing. It's not that much heavier. A price you pay for a huge screen in your transmitter, and it is BIG!!
After using my M11 for a little bit I like it better than the M8. It is heavier but the balance is better. The radio doesn't fall foward like the M8 during the main. At first, I thought my M8 felt better but after 20 minutes of driving, the M11 was in the same position in my hand as was at the start of the race.
I'm still Ps'd about the dual rate and brake trim. It feels uncomfortable to use and is far more difficult to adjust during a race.
Loved my M8 but my new M11 sure does show improvements. Battery compartment much better than the flimsy cover on the M8. Backlit and overall functions and similarity in design make this a great upgrade to M8 users. I can still use my novak module and its all good. Cost aint that bad either. Suggestions to those M8 users or other folks that think its too expensive. Sell your M8 on Ebay so you can get the best value from it. I believe the M11 will make the m8 prices drop like crazy once more and more m11's are available in stores and online.
