I recommend that you use your hands to get your flaccid length longer so you can attach easier in the LENGTHMASTER 3 later on. You can probably attach in the LENGTHMASTER 3 now as well, so I recommend either way that you buy it.
You can also use Power Assist 2 to stretch with.
Stretch in every directions 1 hour per day (6 days on, 1 day rest). Transition to bundled stretches and use the Power Assist 2 to get more intensity in the stretches.
I recommend you to get LENGTHMASTER 3 and the SiliStretcher. Use the SiliStretcher to heal elongated. You will get Power Assist 2 when you buy LENGTHMASTER 3, since Power Assist 2 is one part of the LENGTHMASTER 3.
When you say girth 2" and 1.7" do you mean diameter? No you probably don't mean that. You are saying that your erected girth is 2" and flaccid girth is 1.7"?

Do this routine without the broomstick 1 hour per day. Split it up, do 20 min x 3 or 30 min x 2.

Increase the stretching force as you progress. When you feel it's time, you progress into bundled stretches with the Power Assist 2.
For girthwork you do this routine once per day:
