Get your liebig for distillations.... a nice 40cm would suffice for nearly everything.
Allihn for distillation would be a pain, the distillation gets trapped in the bulbs... and hence removes the functionality of a fractional distillation.. use the Allihn's for reflux.... 60cm should do it well.
Maybe even instead of a second Allihn, a double surface condenser for more delicate distillations, just so you have that extra edge of cooling capacity... a 40cm one of these should be fine too....
With these three condensers (40cm liebig, 60cm Allihn and 40cm double surface) you would have a nice varied collection for pretty much everything you want to do, reflux's and distillations.....
