Sumiko Headshell on SL1210

Hello folks, i have this on my deck and it does make a big difference, but here in the uk for some reason we don't get the extra counterweight it's an extra. i use an audio technica 110e with this deck and very nice it is too so i am waiting for my friendly local dealer to source me a weight, hopefully for free so by reading some of the posts here do you use blutak as i do to balance the arm or is there another method i could use. great site by the way. all the best, engine
