I use a silex superba, minor differences between it and the silex, but the premise is still the same. I've been using it for roughly 20 or so years now without a hitch...
Funny enough, some of the pros are also cons, depending on your perspective...
Pros
-Closed face reel, no birdsnest of line coming off the face when you aren't paying attention...
if you have that problem.
-Large line capacity
-Handles are set in from the rim, allowing for better "purchase" on the rim with your fingers without the knuckle busting effect of other reels when that fish goes on a tear...
-Bullet proof. Solid construction. I fell badly once on the cheakamus about 12 years ago...landed on the reel and took a little chunk out of the inner rim of the spool...

no warping of the spin, no other damage, reel works like a dream to this day.
-Bushing design, Spin improves with usage
-Good clicker design, doesn't get in the way, no need to look for it...
Cons
-Closed face reel, you'll have to learn some new close quarters casts to replace the "strip line off the side and get it spinning" cast that works so well with the open faced reels. Not a problem, plenty of casts to work with.
-Handles set in from the rim. Some people complain about this. Seems they think it makes it hard to reel in. Something most would get used to over time. It never bothered me, not even when I first started using it. In fact I prefer it that way.
-Likely won't spin as well as the newer bearing reels, a slight bit slower off the start but more than adequate for all conditions...you'll learn to use that space on the rim to speed up or slow down the spin as required.
-Gotta work them in. Fishable right off the bat, but do need to be worked in to achieve optimal spin.
-Clean it regularly, I do about 3 times a year or so just to keep it performing optimally.
Having used this reel as long as I have, I don't even really consider the cons to be cons...right from the start the reel performed great for me I've never had any complaints or concerns about it's abilities.
I prefer it to the new bearing and bushing style "pins"...it has style and a classic look and it will never let you down.
Be sure to check the reel thoroughly before buying. Look to make sure it spins true, sound advice for buying any used pin reel...otherwise it's a great option for anyone wanting to get into a centerpin reel.
