Hi,
I dunno about anybody else, but personally I could never get used to using pencils + CRP... I've always found it much easier to use a fine black ink permanent marker, making a single 'dotted point' as opposed to a cross where I want it.
Much easier to see, and if you wet your finger first, it will come off no problems within about five minutes or so of being applied. And honestly, how long are you going to be using it for at once - perhaps for 30 minutes of the navigation exam?
Just my thoughts, and to answer the original question, yes, I would definitely reccommend the CRP-5
with windarm.
I may be ignorant here, but how else would you work out W/V probs? Trigonometry!?! Haha don't be so silly... oh, you're not joking...
