My first 'real' post - be gentle with me

I have a current port goal which is to find a replacement for my beloved Warre77, so I thought I'd post about my plans and experience so far in case it's of interest and for any suggestions/comments/advice which would be welcome.
Warre77 has been my staple (affordable) favourite for the last decade; It's now starting to be in short supply, so it seems like a good time to try and find what else might be able to take it's place. Of course, I like trying many different ports, and would go for many older ones if budgets allow,but financial pragmatism also has to play its part. So previously, while say Fonseca 70 would have been my likely ideal choice, Warre 77 become my firm favourite since while very different I found I like it almost as much as the F70 and was much better value.
So how to find a new favourite? well, try more port ofc - such a drag

1. I'm looking for vintage, not ruby/crusted etc, as my experiments with the latter were not positive
2. On price grounds (as well as availability), it would have to be newer than 77
3. To be good enough, I'm expecting to look at least 15yr old, probably 20yr old+
Having looked at the options, years, vintages etc, along with what I have/haven't tried previously, a couple of things stood out:
- There were a few I'd already had, including various 83 (incl Warres, Fonseca, Grahams?), Fonseca 85, Fonseca 94; all were good, but none stood out as 'the one'
- I've enjoyed Grahams 77, 83, and not tried any newer
- I hadn't tried *any* Nierpoort
- The 94's are really only just really entering the criteria age-wise, are supposed to be a very good year and I'd only tried one
I decided therefore to try and fill the gaps, with a bias towards 94 on the grounds that this is supposed to be a superlative year, and am therefore planning over time to try at least Nierpoort 94, Grahams 94, Warre 94 and Warre 91. This gives me a chance to find out what I think of 94 generally, try a Niepoort, and a double-shot for Warres since I've enjoyed it for so long plus the W91 was supposed to be good.
So far, I've had two of them, with the following results (very brief taste notes - I don't flatter myself of the capability of description of some):
1. Nierpoort 94
I was pleasantly impressed with this; Seems lighter in initial intensity than I'm used to, but has a lovely smooth complex flavour with a long aftertaste. Has definitely made me want to try more Nierpoort. This would be a definite candidate, only negative for me being the initial lightness.
2. Warre 94
Very intense flavour, both initial and aftertaste; Very strong flavours of Vanilla and blackcurrent/berry; Not as 'earthy' as the 77. I still enjoyed drinking the bottle, but found the vanilla too overpowering; not a candidate.
3. Grahams 83
Unfortunately partly corked, so difficult to make any real valid judgement. Compared to the 77 Grahams tried previously extremely favourably, this was surprising dry (not the sweet stickier taste I expected) with a very closed intense dark flavour; however since partly corked, no idea if this is typical. Ideally would like to retry.

Further tastings at offlines now only added in usual places. To summarise, to date two suitable replacements have been identified, an a runner-up:
1= Calem 85
2= Morgan 91
3 [runner up] Warre 91
However, since both top choices are essentially unavailable for purchase, the "runner up" of Warre91 is currently top candidate, although it is only really just ready for drinking now, but will likely become a future staple. A case of Warre77 is planned in the interim while stocks last
