In my continuing quest to lighten up my beloved 65 SR (I'm the original owner) I'm considering a half cabinet with 2 10s. I am not looking for early breakup. What 2 tens would handle the load about the same as 4 ?

Are you looking to use those original speakers in the 2x10? They may not handle the power.
The amp will likely sound different, driving a 4 ohm load rather than a 2 ohm load.
Have you considered having seperate head cab and speaker cab for the 4x10s, to ease handling? It makes a big difference.

How about replacement speakers with Neodymium magnets?
Depending on what you have in there now, you could cut the speaker weight in half.

You could do fine by ordering a set of 4 ohm 10" speakers from Weber - lots of choices in your power-handling range.

I realize I would need 4 ohm speakers to keep that proper, but maybe double the wattage? Again, I want to keep the clarity at a similar level to what it is now.

You will find the amp to be less loud. If you are into clean headroom I would not make this change in a combo. I'm afraid it will sound nothing like the SR you know and love. (except the weight)

I would find myself grabing more volume knob to compensate and you say you are not looking for early breakup. A head cab and then any type of speaker cab you wish could be used with reasonable speaker impedence.

I'd get a dolly to move the amp around with rather than bugger a '65 Super Reverb.

Take your amp to a local large guitar shop and try it with different 10 and 12 inch cabs. Se how it sounds. I hope you are going to leave you current combo stock?

I'm not concerned about the stock thing, the amp is decades away from true stock. BUT, I'm not going to cut the cabinet in half. Would either build or buy a custom cab and put the parts in it. I prefer the simplicity of a combo. I'm just trying to get some ideas as to what speakers to consider.

I think, if you get 2 speakers that handle the SR's power as well as the two that are in there, these two speakers finally may have same weight as the 4 originals.
Not knowing what you actually have, but a Jensen P10R RI is rated at 3.1 lbs, a C10Q at 3.6 lbs - makes a total of 12.4 - 14.4 lbs for that typical 10s that I expect to find in a SR.

Now a cool speaker that keeps up with volume and wattage in a 210 configuration might be a Ragin Cajun (2 x 6.4 = 12.8 lbs) or a Copperhead (2 x 4.5 = 9.0 lbs) or a Jensen Jet Blackbird (2 x 6.6 = 13.2 lbs).
So there is no saving in weight or best approx. 3 lbs.

So I doubt whether the weight is really worth the downsizing. IMHO an ideally downsized SR would include also a smaller OT, 6V6GTs and a smaller mains transformer together with a 210 configuration ...

As it is, I'd vote for the head+cab transformation ...

Edit to add, yes, or get a Vibrolux :)

I'd get a vibrolux instead of putting a super in a 2 x 10 cab...

I had a buddy in Denver with a 65 BFSR chassis in a custom cut down combo cab with 2x10 configuration. One of the best amps I've ever heard in my life! No shortage of headroom.

The 2 speakers were Weber Ceramic Cali 10 and Alnico Blue Pup at 4 ohms each.

edit to add - he still has the original cab and cones

Yes, the OP wants to retain clarity so best to keep with big iron.
But really, reconsider the seperate cabs idea, I find it so helpful; combos bigger/heavier than a DR are a pain to maul around and it gets harder the older you get. Pete.

I'd build a 2 x 10 cab and and "head cab" for the amp. Separating the amp and speakers really helps lighten the load.

Regarding the speaker I'd take a look a 2 higher wattage speakers myself.

I know it came with 10s, but would you consider, say, a single 15" neodym?

Thanks all, I've got some great ideas for an approach now. Of course, at last nights gig I was reminded of several important aspects of a SR (besides the sound)
I don't have to bend over to adjust knobs
It's a great mixer stand
It's a great cocktail table

And there's that sound....

I have a '69 Super Reverb chassis in a Mojotone Vibroverb cabinet with Jensen Neo 15. It is still a heavy amp, about 48 lbs., but lighter than a stock one. I use a Weber Z-matcher because the Neo is 8ohms. I'm happy with it. Very clean, with lots of punch. Highs are smooth, takes pedals well.
