Les here is what I found as far as skinny comb was concerned. The few skinny combs were the ones which were at the tail end of the flow. (Left overs if you will), I did not have very many of these.
Honey Pump Beemaster2 and others recommended the three inch, backward comb uncapper, if I remember correctly.
I ordered both sizes just for experimental sake. I found as long as most all comb that was filled during the jest of the flow, (full figured comb), was pretty easy to uncap. (Except previous brood comb which was a pain).
The skinny, uncapped ok up to a certain distance from the edges, depending on just how skinny it was. From there the tine scratcher finished the job. I was pleased with the combination. Still, take into consideration my experiences were limited. Until last season I had used the (scrape it down to foundation method). Primitive yet effective, except once again, x-brood comb.
So in my experience x-brood comb is a hassle as compared to strictly pure honey comb. Therefore my interest in the Lyson Manual tabletop steam uncapper.
Adding: From the recent topic, Single brood box, X-brood comb was in the back of my mind and main reason for asking HoneyPump, (in my reply 7 there), what was done with the upper brood box when the queen is pushed down, while adding the QE in that recent topic. I am assuming the second, top brood box is left in place for reasons I had stated as assumed on that topic and reply. If the Lyson will slide effortlessly through prior brood comb, that will be grand!
