Tut tut Kazzie... 763s?! I shall have to inform the pier co-ordinators to keep an eye on you!!!
Never had a problem with 733/4/5s myself - as long as the left hand edge of the canopy is on the panel join just aft of the pitot tubes you'll be bang on
Fokker 70s are a pain in the backside, as are 744s. Never really liked doing MD8xs either but you get used to em all.
For real s**ts and giggles, try bridging a Tu-154... now THAT is entertaining!!!
As for the easiest... 736/7/8/9 and A318/9/20/21, easy peasy
(used to do between 5 and 7 763s a week until recently... 
)
