I’m building a retro bike packing bike.

I plan to use some XT thumb shifters but I’m a little insure which shimano levers to pair them with?

Which xt thumbies: 6 or 7 speed?

6 speed M730 4 finger bad boys (Kit Kat)
7 speed M733 2/3 finger poster boys (Twix)

As above, M733's would be my choice. Dia-Compe SS-5 or SS-7 are another option.

The 4 fingers were an option for the 7 speed too. M732 vs the 2 finger m733. Both had SLR pistons in them (which m730 didn't) ....so it also depends if your using SLR cantilevers with the twin position internal spring holes or not.
