SRD sounds like a good idea. I am in a smaller city and am having a hard time finding anybody with good info. If not balsa what else would work good? I know everybody has their own ideas and I am open to trying almost anything.
Leather, or felt , as matter of fact will work better for newbie because balsa is harder and less forgiving for uneven pressure while stropping.
You can also apply CrO on the linen component of a hanging strop.
