The Volquartsen bolt release is wonderful.  No more fumbling around with
Ruger's little sheet metal sliver, trying to get it to engage or disengage.
 Simply pull the bolt back and push up on the bolt release:  The bolt stays
back.  When you're ready to chamber a round, pull back on the bolt handle
and let go.  The bolt release drops free and the bolt flys home.  Great!
The Volquartsen hammer gets mixed reviews.  Trigger pull is noticeably
lighter at 3.5 lbs., but the break is creepy and still a little gritty.  I
attribute most of this to the sear on the Ruger, which is rough and has
what appears to be casting flaws in its surface.  I intend to stone those
surfaces smooth and coat them with Brownells Action Magic dry lubricant.
More on this later.
In summary, the heavy barrel conversion has resulted in a very accurate
semi-automatic rifle, so much so that accuracy is more limited by my skill
than by the capabilities of the rifle.  The balance has changed to a more
muzzle heavy bias that hangs much more steadily in off-hand shooting
situations (even in 30 mph gale winds!).  The Clark chamber allows any .22
Long Rifle ammunition to be used, unlike the Clymer supplied Bentz chamber
being used on some other barrels.  These require more expensive match ammo,
for whatever reason (I suspect that the Bentz reamer results in a slightly
shorter throat, such that longer plinking grade bullets may not fully
chamber.  Comments on this are welcome).  Would I do it again?  In a
heartbeat!  Even with the disappointing trigger feel, this is still one
heck of a rifle.
