Replying to Is 186 cm HG stingers too big for me?

Hi I'm a skier from New England. I ski a lot in the park and occasionally everything that the mountain has to offer. I'm considering buying HG stingers because they are a core brand and their durability on skis. HG stingers only sell in 186 cm long skis. I was wondering if 186 cm long skis would be too big for me because I am 5'6 and weigh about 135 pounds? I ski pretty aggressively and I'm currently 19 so I don't think I will be growing taller anytime sooner. Currently I ride 164 cm skis. Please help. If you have any other comments about HG skis please let me know. Thanks.
