Flexradio 6300 review for contesters

Some findings from my first contest with the above setup: 1) No focus return to SSDR from N1MM+ despite have the having this set to N1MM,UDP port 12060 and 1000ms in radio setup dialogue box? I'm new to N1MM+ and SSDR (usually use K3 and WinTest, but the soft winkey doesn't work properly with it) so found it really frustrating having to use the mouse to constantly have to click in the N1MM callsign field every time I touched a control in SSDR. Learned the up/down arrow keys were RIT in N1MM which helped. This is mad as took a few Qs to know that up key was RIT down??? It occurred to me that successful contesting with a Flex really lies in knowing all N1MM+ key strokes to control the radio (need to look into this to see how much of the flex can be controlled from N1MM i.e. filter width etc). 2) The soft winkey seems to work 95% of the time. When it doesn't work it always seemed to have a glitch on the first letter of sending. Every 20 qs or so would mess up causing me to hit the esc key and send again. Setup shouldn't cause varying results? What I was hearing seemed representative of what was being sent as it almost always resulted in them sending their call again. This was hampered by the sidetone sounding distorted and gravelly during the switch from rx to tx (noisy contesting conditions) so it made it hard to determine if there was a sending mistake with the first letter. 3) Noticed on several occasions that I could see better than I could hear. I could see the blip on the screen but couldn't hear it (despite it being in the passband but slightly off center). After a while I noticed that small differences of RIT would then allow me to work them??? So without the bandscope I wouldn't have known something was there to alert me to fine tune RIT. I've never noticed this with the K3 and P3 combo, I could always hear what I could see in the bandscope....amazing/hole in hearing/problem with FFT taps not overlapping and factored properly???...I don't know! 4) One of the massive advantages of this radio is that controls in SSDR work during TX. This used to frustrate me with radios like the K3 who's implementation locked controls during tx. Its been a long and rocky road with the 6300 so far. The latest sw/fw has given me a working radio for the first time in my 4 months ownership (broadband tx splatter fault, hardware fan failure, sprung bpf filter board etc etc). There is no comparison with my K3 rx performance however, with blocking and noise level bouncing up and down evident on the flex with strong adjacent stations (contest conditions). I know its not a fair comparison, the 6300 was my toe in the water with SDR and I'd need to now move to the 6500/6700 so as not to compare apples with oranges? I think I need to do some reading on N1MM+ and determine its extent of control of the flex. This will be the deciding factor for me of whether or not I can use it successfully for serious contesting. Maybe also I need to purchase the flex control tuning whee,l but whether app focus works with that now worries me.
