Torridon jumble has the highest concentration of problems, mostly within a 5-15min walk from the car. Only issue sans pad is that a fair bit of the ground is boggy so keeping shoes dry could be an issue. Saying that, if you hunt around you'd find plenty of suitable options.
Applecross boulders are more spread out but you'd find planty to do. Again, boggy ground would most likely be an issue.
What are your travel arrangements? Are you hiring a car? I live not far off the road you'd most likely take from Inverness to Applecross/Torridon (near Contin) and could lend you a pad. Drop me a PM if you fancy.
