MkII outhaul issue: difficult to launch in mast furled sail

Hi all, purchased a new to us C36 MKII 2005 and looking to make some upgrades to help us this coming sailing season and need the advice of the group.

Launching the main sail was very difficult this summer from the cockpit.  The Boom Car seems to operate freely but looking at the boom interior it appears (and tech data supports this) that the line runs from the car at the clew through a sheave at the aft end of the boom straight thru to the fwd end where it rounds one sheave and exits the boom to the block on the deck and then aft to the cockpit.  I believe, right or wrongly, that this setup would be better if there were a 2:1 at least (or more if possible) blocks in the boom.  The tech data does not have any options to do this so I am hoping someone has taken the task on with their MKII boom and could share their wisdom.

I have a tech drawing that I hope shows.
Thank you all in advance.

John-
There's lots of posts regarding the in-mast furling mainsail. Here's some summary comments;

-Ease up on  the halyard tension when furling or unfurling. This can make a big difference.
-Unfurling/furling is best accomplished when heading, at least partially into the wind and the mainsheet is eased. The more into the wind, the easier the furling.
-When furling, maintain some tension on the outhaul line so the sail wraps tightly on the furler. A loosely wrapped sail can bunch up inside the mast and jam things. 
-The boom angle plays a role. It should angled slightly upward via the topping lift or vang. This of course will effect sail shape, so the smaller the angle the better the sail shape, but the more difficult to furl.
- When everything is set correctly, furling is relatively easy.
-A  2:1 block system would certainly provide some welcomed mechanical advantage, especially on the outhaul. Boom angle /line adjustments wouldn't have to be so perfectly set, and you could probably focus more on sail shape. My boom is in the basement for winter storage. If I can figure anything out, Ill post it.

I'm with the Keysers on this... the main problem  I find is the mainsheet halyard is usually the problem... ease the tension just a bit and it helps a lot.

I have found that furling and unfurling on a slight leeward tack is much easier than on a slight starboard tack as the sheet binds less on the mast. (The less the sheet blows against the mast the better.)

Interesting observation. One tack will push the sail against the mast and create more furling friction vs. the other tack, which would be more free of mast/sail contact.
