I am planning to redeem NW points for a business class ticket next June to Bishkek (FRU)

The options right now with available seats for my dates are

YYZ-SVO-FRU - all on SU
Aircraft is 767/320
YYZ-AMS on KL 777 then -SVO-FRU(SU) on A320s

Any preferences around here. How does SU 767 business class compare to the combo of KL 777 + SU A320 ??

The first option has a 12 hour layover in Moscow, so it will require a $55 transit visa and I'd get to go into town (havent been to Moscow since 2002).
Its also a longer overnight flight, and saves about $25 in AMS taxes.

The second option is a later departure (10:20pm vs 7:50pm), and has only a short time (4 hours) at SVO (which by that time hopefully will be SVO3), but it would mean 2 redeyes in a row.

Which one would you choose?
