Hi Reefman,
with the spool in the "low" position, thus closer to the reel, you'll find that the line at the bottom of the spool, will "knock" the side of the bail arm mountings during the cast, especially with reels filled with mono. This has an impact on the distance you can cast.
To A1, can I assume that you'll be fishing with braid (using the bionic finger) - if so, remember to slightly under fill the spool by ±1mm-2mm so as to reduce the possibility of wind knots.
All the best
