Drifts for front wheel bearings/seals-drum and disc?

I see SIP sell a few different drifts for fitting new bearings to the front hub and front hub backplate of P ranges.

I have both a front 20mm drum and a disc setup I would like to fit all new bearings and seals to both (hub and backplate-main and roller bearings on both)

Don't want to buy the same thing twice so

which ones should I buy to cover all I need?
