Thank you so much for all the replies.
I preferred to descend to a lower altitude to keep high speed.
The lower the altitude at which you intercept the glide, the faster you can fly until then. Instead of extending flaps to 5 (737) and descending at 180 knots from 12 NM out, I kept 280 knots until level at 2500ft, then slowed down. Worked nice.
