Thank you for the info! WinSCP by default has this cipher selection list in order of preference: AES, Blowfish, 3DES, then DES.

One question though: is encryption necessary anyways since I'm connecting through wifi with WPA enabled?

My test using WinSCP and various encryption methods:
AES 310KB/s
Blowfish 345KB/s
3DES 210KB/s
DES 345KB/s

Selecting 'compression' slowed down all the transfer speeds.
