Managed to get myself an 8/9 switch just recently, am still not sure what lines really suit it best, the switch line I got for it is similar to the set up you describe, a short stout belly with three tips to suit, not to happy with the performance overhead though. have an old two weight D/T line here somewhere might weigh it up and try it as you describe. although an alternate longer belly using the tips I have already might be another option. The winter is long I guess.
I have been away for a bit and apologize for the late reply.
I have been mainly fly fishing with 'short' double-handed rods since 1959 which is puzzling since our American cousins seem to have only very recently 'invented' the concept.
If your switch is performing reasonably well roll casting ( whether Spey Or Underhand cast)you will find that the overhand cast requires considerably LESS weight. If your fly line roll casts well at a given weight it is simply a matter of retrieving several feet of line 'inside' the rod tip to execute the overhand cast. Presumably your joins will be sufficiently streamlined so that will run easily through the rod rings
This is because with the Roll, Spey or Underhand Cast (aka Göran Andersson) several feet of line or leader is attached to the water surface as anchor to your D Loop - and the D loop is the part which loads the rod. However with the overhead cast you aerialize ALL of the line and therefore you have to subtract the amount weight which makes up the anchor or the rod will be OVERLOADED.
