I have points and they are brilliant but you can't use a stand off with them. If you have wfp then there is no real purpose to getting pointers, save your money and get some good trade ladders.
Triple 12 would be a good idea, they'll take you up to 30 ft if you have
someone footing, and above 30 ft you can't do off of a ladder. You can normally split triples down to a two section as well to make it a double 12 which is a really good height.
