Wow this forum really works, 6 great answers over night!
Thank you everyone!
That's what I suspected, but it would have been so cool to pick those up at a store today...!
I'll definitely go with the Options interchangeables, but I'm thinking of starting with ordering a longer cable than what's in the set and only one pair of needles and if I like that, then get the whole set. I'm quite sure I will like them.
Again thanks everyone for your input - I'll order this right now.
