I know that I need a Boss "F" series footswitch for my new Roland Cube 40X (FS-5U, FS-5L, or FS-6). However, for the looper, what footswitch is going to be the best? A single or double footswitch? latching or unlatching?

My Gear:
Fender American Deluxe Stratocaster
Epiphone Sheraton II
Fender Blues Deluxe Reissue
Teese RMC Picture Wah
MXR Carbon Copy
Keeley Modded TS9
Korg Pitchblack
Schecter Omen 6
Dean Performer Acoustic

A double will be more convienet because one switch can activate the looper and the other can stop or clear it.
