Good points you make there mate.
Would point out something about Vardy and players with pace in general though, a lot of them 'seem to age' a lot earlier than other types - but often it's a case of chicken and egg, as they have a tendency to pick up a lot more injuries such as hamstrings - which ultimately tend to plague them and long term slow them - so is it a case of it being exasperated by that factor, Owen a very good case in point, as is closer to home mirallas - who if you just looked at him - he has clearly not only slowed in general but 100% lost that explosion of pace which made him dangerous.
Which brings back the benefit of Vary having not played for that long at a really testing physical level, he's stayed clear of injury and as much as it can be said is extremely fresh for a 30yo.
We do indeed need and seemed to have been after a quality target man type, my assertion is, if we can't get one and the next best option is a journeyman type, then we'd be better served by bringing in the best available player who gives us dramatically different options to anything we currently have - which Vardy certainly does, and also one who is better than anything we have in that position by quite a way in what he does.
I wouldn't worry about the finances of such deals mate, we appear to have gone with a distinct plan to bring in two different categories of player - in regards to age, ones with a certain market value increase, and ones with the current ability to effectively pay for their prices by improved results and performances on the field right now. Ultimately they will not be sold for close to the amounts they where bought for, but the club seems acutely aware of this with the recruitment into the Under 23's going into absolute overdrive - as indeed has the level of teams we are beginning to loan players out too, in order to gain them experience and ultimately increase any future sale price should they not be deemed good enough for us.
As for the worry about sustainability, i would scratch that worry from your mind for now mate, we don't have the richest owner ofc, but what we do have 100% is the owner who has the shrewdest mind in terms of accounting and ensuring things aren't put at risk.
