I flew an A36 Bonanza for about 350 hours and I would always get 170 to the marker also.  What I would do was set it up to get to 20" and 2500 RPM at the marker with a power reduction of 1" per minute starting out at 25" so it took about 75 minutes of planning before you get to the marker.  You have to be in a decent the whole time before you get to the marker though otherwise you will not be able to keep the 170kts.  When I would hit the marker I would level out until I got to 154 the 12.5" flap and gear speed then put the first notch of flaps in and bring the power back to 18" and that would keep me at 150 on the approach until I got to about 1 mile final then dump the gear and then it slows down fast when you get the gear down and bring power back slowly and get to final flap speed on about 1/4 mile final.  I never had a problem getting that airplane slowed down if I had the first notch of flaps in before I started down after the marker, but if you wait you will never get it slowed down without hurting the engines.  I am not sure what engines you have in your Barron, but if you have the IO-550's they don't like the power to be pulled back to fast since the cylinders run hot and you will shock cool them and do damage, but if you have the IO-520's they can handle a little more then the 550's.  Hope this helps you out some and if you have any more questions just let me know.
