Looking for a suggestion/ideas!

I'm in Europe right now, and want to go back for a quick 4 day weekend back to bean town... I'm wondering whether I should go C, or just stick it with Y, or a combination!!

My options so far are basically:

Westbound:

BLQ-FRA-ZRH-BOS in C, with ZRH-BOS being LX A333
BLQ-FRA-IAH-BOS in Y, FRA-IAH being on LH A380 (kinda neat and a gillion miles)
BLQ-FRA-BOS in C, FRA-BOS LH old style C on 744
Or a regular BLQ-MUC-EWR/IAD-BOS on UA in Y

For westbound flights, I don't really mind Y, especially with UA E+. However, I've not been on LX new C class and I hear only good things! Arriving directly in BOS is a plus as well!

Eastbound:

Could only find UA, either from EWR, IAD, ORD, on either 772, 763 and 752. I haven't been on C on the 752, and AFAIK the 763 is a PmCO retrofitted flatbed.

Prices right now are $1000 in Y, $3000 in C or about $2200 in C/Y.

Any suggestions would be welcome!
