Wotan - Of course you can match them up. The usual excuse of you cant always do that is used to try and justify multiple variants wanted for the same year, or people wanting some of the more exotic aircraft.
I have no idea what you are talking about at this point...
You asked in the original post:
what are your thoguhts on the 109/190 opponents for them?
My list:
1940 - Spit I (+12lbs boost as of March 1940. All Merlin III fitted with C.P props by August 1940)
1940 - 109E-4 (May 1940, Also most of the earlier Emils were upgraded to the E-4 standard during the summer of 1940)
1941 - Spit Vb (12 Ibs, February 1941. 2 SQN The British Fighter Since 1912. Mason)
1941 - 109F-4 (1.3ata, the first F-4s reached the front line units in June 1941. Prien & Rodeike)
1942 - Spit F IX (May 1942. 81 SQN The British Fighter Since 1912 Mason)
1942 - 109G-2 ( June 1942. The first units, III/JG 52 and I/JG 54, received their G-2s in June 1942. The first loss reports are from July 7th and 8th 1942. Prien & Rodeike)
1943 - Spit LF VIII (?)
1943 - 109G-6 (G-6 Entered service and saw action with II/JG 53, II/JG 77, JG 27 and JG 51 in February 1943. Prien & Rodeike)
1944 - Spit LF XVI (18 lbs boost ?)
1944 - 109G-14 (G-14 entered service with II/JG 11 and Stab/JG 53 in July 1944)
Late 1944 - Spit F XIV (21lbs boost ?)
Late 1944 - 109G-10/K-4 (October 1944 / K-4 Entered service with III/JG 4, Stab+I,II,III,IV/JG 27 and II/Jg 77 in October 1944. Prien & Rodeike, H. Valtonen)
That list is not only practical it terms of demonstrating to the unwashed masses what's what but you won't get any more 'historical' and/or 'practical' then that.
OTOH you say:
The dates are service entry (just did by year and picking the most produced version of Spit).
I reply:
It doesn't really matter if its service dates, or or most produced during a given year, or even if the VIII's real opponent was the G-14.
Meaning that if you get the Spit line up you expect, a 109 line up as I described would be the best alternative and a direct answer to your original question.
You then say:
Actaully if you think about TOD, I suspect you'll find that he IS looking for a historical matchup.
My reply being is the 109 line up I suggested is what ToD / Scenarios and events would need both historically and for practical purposes...
Now what is it you are going on about?

The Spit LF.VIII that AH could stand in for the Spit LF.IX... An easy 'historical' match for the G-6...
the Spit LF.XVIe CW (stand in for the Spit LF.IX CW) that Guppy suggested would fit well as a match to the G-14...
A 1944 Spit XIV @ 21lbs boost would match up well with the G-10/K-4 (perked or unperked...)
It doesn't matter if the VIII was used in the Pac or even if the Seafire III was. A Pac Tod is a long way off. In the mean time these planes will have use in WETO/MTO. As such the 109s I suggested fit well in establishing a some what historical counter to each other...
And no they won't remove the 152, why would they..? Its useless for ToD and events and only gets play in the main. What difference does it make just by being in the plane list that would require it being removed?
At this point I am not sure what it is you are saying. I made my suggestions and they are all as 'historical' and as 'practical' as AH is gonna get given the expected new Spit line up...
