I aim for 180 kts(no wind)on the glide,if there is a 20 kts headwind i can accept 200 kts until about 7 miles..
If you are high initially use speed 250 below 10 and speed brakes but aim to catch the glide at a proper speed...if hou have to,decelerate to clean earlier,lower the gear then reassess your profile...if you are still too high throw in some flaps...if on profile,manage to do a continuous descent..
