How many diffrent gauges do you have and what do you use them for? Like on the PT heads or kayfun or rba's. What would really be the diffrence in using diffrent sizes? Right now I have 32 gauge and so far it has been fine. About 6-7 wrapes and i get about 2.2-2.5 a little higher than i want but been fine. I am thinking of getting some 28. What would be best?
