I know that this is a newby question and really annoying for the pros around. I know that this general question gets asked all the time and that I should use the search tool. I have. I didn't find quite what I needed. So I appologise in advance for a very boring question. I'm interested in getting some weed-whackers but my teacher seems to have a prejudice against them. He suggested "D'Adario helicore hybrids" but from what I can tell (which is very little) they seem to be the same as weed-whackers. I may be wrong, but if he is suggesting the hybrids, how different are they from weed-whackers? Weed-whackers are about $100 Aus cheaper for me to get and they seem to have a good rep. What should I do? Get the D'Adarios, the whackers or just "shut-up, Newbie?"
