I have used a narrow bottomed double pointer ladder and you MUST keep your  body weight within the stiles. They can twist if you stretch too much  .

not if you use them properly. i think (and is only me view) that standard ladders are safer/better than pointers.

get a good ladder, not some cheap and too light rubbish.

its your safety and is best to get the best you can afford.

you really are best off finding someone local to help you out for a day or two - can get the hang of window cleaning and you sound like you have never really used a ladder before.

time is money with window cleaning and if you are too slow up and down a ladder you wont make alot of money.

we all make window cleaning look easy but it can be hard at times

alot of chaps now go straight for wfp cleaning.

Dont know why you think pointers are less safer than standards ones 

They are made for window cleaning and are very safe. With normal ladder you place the top of the ladder at the sill or above the window, both of these can be very unsafe, where as the pointer can sit on the vertical frame or to the side of the fame, making the job much easier.

Just my opinion tho 

yes total tosh in my opion  too - ive been on points for 20 years plus - you would never even get me up a normal ladder even doing things round the house !!! uneven ground , sloping paths they can go anywhere.
